1. INTRODUCTION
The
year of 1986 is the Halley comet year. The history of cometology
retained the following curious case. In 1910, when its (i.e. the
Halley comet’s) previous visit to the Sun took place, one of the
March numbers of a newspaper “Golos Samary” (“The Voice of
Samara”) reported, that a certain monk sold shrewdly at the central
city square the leaves of “Charm against meeting with Halley comet”
of the following content: “You are devil! Satan! Never world
Velzewool! Don’t feign you are a celestial star! Don’t deceive
the Orthodoxes, hide your godless tail, because the God’s stars
have no tails…Dip your tail into fiery river, let it reduce to
ashes, let it char, let it fry! Etc…” This curiosity was
reprinted by “Russkiye Vedomosti” (“Russian Registers”) on
the 3-rd of April, 1910 and went down in the history of the Russian
science.
It is interesting to note, that the next
visit of the Halley comet was in 1986 and coincided with the 400th
anniversary of the city of Kuibyshev (formerly and now afresh -
SAMARA! – rem. A.G.).
The author of
this article, living in Kuibyshev, dedicated to this significant date
the application for the discovery “Comets formation phenomenon”
[1,2], which, as the author considers, convincingly confirms and at
last resolves a so-called comet problem.
2. EXISTING VIEWS
(HYPOTHESES) ON THE COMETS FORMATION MECHANISM
In
accordance with the views, which were shared by the most part of the
astronomers before the experiment “Vega” (“Venus-Halley”),
the comets originate from the so-called comet cloud of Oort and
consist basically of dirty ice [3].
This hypothesis
cannot convincingly explain the fact why the comets are grouped
around the major planets of the Solar system (in families of
planet-giants). Besides, the mechanism of comets breaking-away from
the Oort cloud is actually very unconvincing.
The
Nemesida hypothesis (the dwarfish star – the satellite of the Sun)
did not save the situation.
The second basic
hypothesis (S.K.Vsehswiatsky) states, that the comets are the result
of volcanism on the major planets or their satellites. Yet it’s
obvious, that this mechanism demandes too high initial speed.
The
basic hypothesis now, after the experiment “Vega”, is the idea
that the asteroids are dead comets. The author considers this
point of view as an intermediate stage on the way to the truth.
3.
A CONCRETE COMETS FORMATION MECHANISM
The basic
author’s idea is the following: “The comets are formed from
asteroids as the result of asteroids piercing through the rings of
the major planets of the Solar system”.
Indeed, it
is known that the planets of the Solar system can be collided with
small space bodies including asteroids. The major planets (Jupiter,
Saturn, Uranus, probably, Neptune) are surrounded by rings
consisting of separate particles. The rings can also be sub>jected to
collisions with asteroids because they are not the exception in this
sense. During these collisions the rings may be pierced through
because they are not very dense.
For instance, the
thickness of the Saturn ring is about 2-5 km, moreover the stars can
be viewed through them. A typical size of the particles is about 1 cm
(in accordance with the data of “Pioneer-11”).
It
is interesting to note, that the space apparatus “Voyager”
discovered the two Saturn satellites in the ring system, moreover,
one of them is moving in the ring, but the other has a slightly
slanting orbit and therefore it finds itself either at one or the
other side periodically. This circumstance confirms the possibility
of piercing of the ring. The destruction of both the ring particles
and asteroid and the distribution spectrum of the particles by speed
will take place as a result of the piercing of the ring by asteroid
as strong as the concrete circumstances allow. Besides the asteroid
flown through the ring takes off some quantity of its sub>stance. The
small fragments of this collision can generate the meteor flows
afterwards.
A basic part of the asteroid (a big
“piece”) will be soiled by the ring sub>stance and, actually, this
very part forms the comet. Indeed, the chemical composition of comet
tails and major planets rings are remarkably similar: H3O (ice, snow,
steam), different frozen gases and other volatile components (to the
point, the Saturn rings are localized inside the Roche’s sphere for
a liquid body).
The above-mentioned mechanism makes
clear and obvious the fact, that the periodical comets (i.e. by the
type of orbits – orbit classification in families) are
conventionally grouped around the major planets having the
rings.
The Jupiter ring is less dense than Saturn
rings and it probably consists of snow and gas. This partially
explains the fact, that the most of short-period comets (Jupiterian
family) have a faint tail or only have a coma (here it is necessary
to take into consideration the rapid evolution, as far as the period
is short enough).
A periodical variations of glitter
of the Donati and Halley (with 52-hour period) comets are explained
by the fact, that monolithic nucleus of these comets has an
asymmetrical stretching form and accomplishes the rotary motion. This
rotation may be the result of collision with the particles of the
ring.
A basic mass component of a comet nucleus is
determined by the type of mother’s asteroid: stony, iron-stony,
ferrous.
The facts of the division of some comet
nuclei may be explained by the presence of cracks in the nucleus (it
may be the result of the collision with the ring). It may lead to the
thermodeformation in the vicinity of the Sun.
The
orbits of the most part of comets lie in the ecliptic plane or near
it, although the orbits of separate comets are precessing. This
circumstance is normal in the proposed mechanism frames.
Let
us value the frequency of the comets rise. Let us take the Earth
statistics.
In the current century (here – in the
20th century – rem. A.G.) the next coarse enough meteorites fell to
the Earth (on the land): Tungus in 1908, Sihote-Alin in 1947,
Fenes-County in 1948, and some others. Adopting that the water
surface of the Earth is more, than thrice larger that of the land, we
suppose, that about 15 coarse meteorite fell onto the Earth in this
century. Considering that the radius of our planet is nearly equal to
6370 km, we shall get, that on each 2.7.106 km2 of the transverse
section area of the Earth (i.e. the ball) may be one collision with a
space body in century. The outside diameter of the Saturn rings is
nearly 2.74.105 km and the width of the rings is 5 times as great as
the Earth diameter, hence, the Saturn rings area is equal to ~
4.2.1010 km2. Considering the relative frequency (on the unit of the
transverse section area) of the collisions of Saturn rings with small
space bodies (with asteroids) equal to the that of the Earth, and
also considering that the probability of the hit into the flat disk
from the free direction is half as much as that of a ball of the same
transverse section area, it’s possible to get the value of nearly
7800 collisions in a century (i.e. every week!). As a result of this
collisions the ring may be pierced and the comet is formed. Still in
this calculation was not taken into consideration the gravitation and
screening influence of planet-giant itself, the influence of the
mutual speed of collisions, the finite thickness of the rings and the
angle of interaction, the sizes and mass of the asteroid and the
particles of the ring, etc., so the real frequency of the comet
forming will be less, than it is calculated. Considering the real
value even 10 times less, we’ll see, that the figure still remaines
big enough (we discover not more than 10-20 comets every year as
average this refer to all the families taken together).
The
best criterium of the truth is the experiment. The author considers
that the space experiment “Vega – Jiotto” shiningly confirms
his hypothesis. Indeed, it turned out that the nucleus is monolithic
and it has the asymmetrical form, it is darker, than it was supposed
from the “ice” hypothesis. Still the concrete analisis of the
results will be given in the next chapter.
4. A CRITICISM OF
THE REALIZATION OF THE EXPERIMENT “VEGA” AND THE INTERPRETATION
OF ITS RESULTS, GIVEN BY THE ISR OF THE AS OF THE USSR
(Remarks: -
This chapter is, basically, the co-name author’s
article of 20.03.86
About 150 soviet organization and enterprises took
part in the creation of the station “Vega” [4]. The considerable
forces and means were taken for the experiment carrying out. It may
seeme, that the experiment have passed successfully, the unique data
have been received about the structure of comet nucleus. Still, the
author of these lines does not agree with a such synonymous
appreciation, although he doesn’t deny the fact, that there really
as received some unique information.
Even more, than a
year ago before the peak of the events of the experiment “Vega”,
the author formulated and argumentally sub>stantiated the hypothesis
about comets forming in the result of piercing the rings of the
planet-giants of Solar system by asteroids. This hypothesis was
prevented to the ISR and other organizations. Unfortunately the
hypothesis has not been considered at the ISR and author received
only formal letters.
Comrades from the ISR adopted the
ice nucleus comet (with soils) hypothesis among their weapons, as a
dogma, which, ostensibly, was shiningly confirmed by the experiment.
In accordance with this hypothesis, the ice comet nucleus must gush
out great quantities of steam and dust, that was reflected on the
experiment itself: the minimum distance from the nucleus at which the
both “Vega” apparatuses passed by, was intentionally chose within
the limits of 8-9 thou km, although the actual precision of pointing
was not worse than 1500 km. Only apparatus “Jiotto” (although not
without the aid of the “Vegas”) passed closely to the nucleus and
showed the features of a relief: hills, craters.
In
conformity with the author hypothesis the comet nucleus must be
monolithic: stony, iron-stony, ferrous – by the type of mother’s
asteroid. Gases, given off by nucleus under the Solar heating, - are
the result of absorbtion and adsobtion the gases and other volatile
components, composing the particles of the rings of major-planets.
Thus, the ejections from the comet nucleus (“soiled” asteroid)
must be comparatively small. To the point, it is confirmed by the
data of apparatus “ICE” (ex “ISEE-3”), which passed through
the tail of Jacobini-Cinner comet on 11 September 1985 (before the
peak of the experiment “Vega”) the distance of 7850 km from the
nucleus and which fixed an unexpectedly small density of the dust
[5,6]. The experiment with the station “Vega-1” showed, that dust
density is significantly less, than it was predicted by the “ice”
model of the nucleus. In connection with this circumstance author
sent a telegram at the ISR. The mistake may be corrected, inasmuch as
also “Vega-2” took place and it trajectory may be improved so
that photos would qualitative really, still it is no happened…
But,
after all, strictly speaking, even if both “Vegas” would be
directed straight to the nucleus (with the accuracy of aiming equal
to 1500 km all the same the result would be negative: they wouldn’t
hit the aim!) and on approaching to it they would be put out of order
but still the task of the stations would be fulfilled as far as the
information was transferred to the Earth in the real time. Nowadays
the capacity for work of the two stations are no longer of any
importance because the unique chance has been lost… There
were two “Vegas” and each of them passed by the comet nucleus at
the distance of 8-9 thousands km! It may be compared with the
situation when the volcano eruption taking place at the Kamtchatka is
observed from Moscow. It at least “Vega-2” approached closer to
the nucleus then it would be possible to excuse the ambiguities and
sheer blunder of the type: “The Halley-comet has a double
nucleus?!” or “…it seems that the nucleus has no clear
boundaries, - it is similar to a boiling pot” [7] – according to
the data of “Vega-1”. In [8] the following figures are offered:
the time error of the meeting with the nucleus is 10-20 s, a relative
velocity of the approach of SA (space apparatus) to the comet is less
than 80 km/s. Consequently, the possible error of the two “Vegas”
aiming (multiply these figures) is not more than 1.5 thousand km. Why
was it necessary to fulfil such a senseless double? And who was
interested in it?
However, it was proudly declared
that both of the stations are keeping their capacity for work and now
the objects in Universe are searched that might be studied by the
“Vegas”. Still, this declaration sounds as no more than an
attempt to appologise their own mistakes (but to-day we don’t hear
much about these searches). Let us wish the ISR sucsess as far as the
area of the searches is very wide: the whole boundless
space!
Probably the author is a little bit
exaggerating, on the photos of “Vega-2” something is seen and
this was shown for first time by TV USSR on the 24th of April, 1986
(after the program “Vremya” (“Time”)), but in this very
TV-program a sacramental statement was formulated: the comet nucleus
is a dark, coal-like body having the coefficient of reflection
comparable with that of asteroids! But you see, the author of this
paper expressed his opinion on this point even more definitely more
than a year ago! My first letter to the ISR was sent on the 20th of
February, 1985! Then at the same TV-program an incorrect conclusion
was heard about that the comet nucleus was still icy. The same very
thesis was formulated by Academician R.Z.Sagdeyev in [9, p.88]: “…the
hypothesis according to which the comet nucleus is an enormous block
of “dirty” ice of an irregular form has been confirmed…Its
surface is covered by a crust of some refractory material having the
thickness of about a centimeter – the composition of this material
is being specified”. The thesis is repeated with a really enviable
persistence! R.Z.Sagdeyev is echoed by Professor V.I. Moroz the
author of the so-called nucleus model in the form of a “March
snow-drift” [10,11] that at first sight seems to be convincing. But
this is at first sight only! The case is that this model is not in
principle able-bodied! Though I had no chache to pick the nucleus of
the Halley comet with my finger still I declare that the comparison
of the comet nucleus with the March snow-drift is erroneous because
of quite different physical condition. We know that specks of dust
and mud don’t fly away from the snow-drift due to the gravitation,
and the Halley comet nucleus has practically no gravitation
influence, as far as its mass is too small. Add to this the pressure
of vapours being formed and dilating into vacuum… Under such
circumstances even the crust of porous platinum would not keep at the
surface for any considerable period of time, to say nothing of the
impossibility of the process of the crust growth resulting in its
self-renewal, i.e. the “March snow-drift” model that was widely
advertised in disabled and groundless in principle!
Basing
on the theory of the icy nucleus it is difficult to explain the hills
and craters at the surface discovered by “Jiotto”, not by the
“Vegas”, as far as the melting of ice leads to the smoothing of
“wounds” (Mr. B.A.Vorontsov-Veliaminov is of the opinion that
craters are percussive formations).
Probably,
R.Z.Sagdeyev and his colleagues being the focus of attention of the
press and taking a great interest in giving away autographs
were too busy and had no time not only to analyse the materials
which I sent them but even to go deep into their own statements. Let
us recall the situation around the experiment “Vega”: at first
there were a lot of advertising in the press, by radio and TV, then
the experiment itself was carried out and were promised that the
results were to be published soon. Now the racket has been finally
faded and it turns out that to “process the obtained material”
requires a considerable time (more than a year) and the results will
be published in special journals. And nowadays our attention is
switched over to the project “Phobos” (“Fobos”) (writed
in 1986 - Rem. A.G.). As for the Halley comet, it turns out that the
answer to all the questions might be finally given
probably only in 76 years when its next visit to the Sun takes
place and we’ll have at our disposal different technical
possibilities - such a “regret” was expressed by the Academician
R.Z.Sagdeyev (wasn’t it done so that not to return any longer to
this an unpleasant for him questions?). I am afraid that this
“regret” is simulated. Still I suppose that tens of millions of
roubles were not wasted only for the sake of vague
knowledge?
However, it is interesting to note that in
[9] R.Z.Sagdeyev writes: “…the inevitability of the objective
tendency doesn’t diminish our responsibility before this (i.e.
communist – A.G.) future…”. Here undoubtedly Acad. R.Z.Sagdeyev
is right. I would like to remind of that the USA are planning to
realize their projects “Asteroid Flieby” and “Comet’s
Rendezvous” earlier than in 76 years – and the USSR may lose its
priority in the science of comets…
A comet nucleus
reflects approximately 4% of the incident light [12], so it may be
conclude that it is a black body of a good quality! And it was really
difficult to call it icy.
In [10] R.Z.Sagdeyev
revealed a turn in his views that is unexpected enough, the
academician writes: “Outwardly it (i.e. the object – A.G.) is
somewhat like Mars’s satellites - Phobos and Daimos (the “Phobos”
– project is in prospect with R.Z.Sagdeyev (in 1986) – here is a
sound logical connection for you! – A.G.) but still more similar
analogues may be some small satellites of Saturn and Uranus. This
keeps within the frames of the hypothesis (I wonder, which and whose?
As far as before this there was said a lot of nonsense about the
cloud of Oort, Nemesida, etc. – A.G.), assuming, that comet nuclei
were formed comparatively not far from the Sun, approximately at the
placewhere the major planets are located – from Jupiter to Neptune,
and then were thrown off at a greater distance during the formation
of these planets” (underlined by A.G.). Any explanation is
needless… For Academician R.Z.Sagdeyev it remains nothing but to
wait a little more and to pronounce quite a fatal phrase: “It seems
to me that comet nuclei were generated out of asteroids while the
latter were punching the rings of the major planets of the Solar
system…” – i.e. to read at last the formula of my
discovery.
In [13] we were told that during the “Vega”
– experiment the amount of steam lost by the comet nucleus every
second was measured for the first time. And the figure of tens of
tons was cited. It would be interesting to know in what way this
figure was obtained as far as there were no direct measurements of
this index (for this purpose it would be ideal to place the
comet nucleus into a sack!). However the author of this paper having
at his disposal such values as the cross section of the nucleus,
integral flow of the solar energy per unit of the area (i.e. solar
constant taking into account the distance from the Sun) has
determined the amount of water that may be heated from 3oK (the
temperature of the cosmic background) up to the vaporous condition
(with the account of all the phase transfers) per 1 second and has
obtained the figure of the same order that in [13], assuming that ice
is a black body (Kabs = 0.96). It means that this figure was simply
calculated in ISR on the basis of their faulse model, i.e. the
desirable was claimed as real.
The apparatus “Jiotto”
revealed the jet escaping of gas (vapours). The intensity in jets may
not be higher than the physical limit caused by the ideal conditions
of the solar heating (as far as the nucleus is not a gas-bag) and
also by the accepted physical model (let it be even a black icy
nucleus), consequently, the intensity out of the jet is much lower
than the physical limit and the total loss of the nucleus mass in the
form of vapour is in any case considerably lower than the figure
mentioned in [13] and which representing the physical limit. Besides,
it is known that the Halley-comet nucleus is rotating and one side of
it is more active [14] and consequently the other is on the contrary
less active. This circumstance reinforces the “activity
contrast” and lowers the index. Thus the figure of 40 tons of the
vapour lost by the comet per one second is exaggerated (and not by
the order!), and if to take into account my hypothesis (i.e. the
nucleus is the asteroid in its basis) it is exaggerated still more.
The “Vega” – apparatuses passed at a great relative velocity (~
80 km/s) by the Halley comet nucleus thus creating their own blast,
the amount of the registered dust and gas is to be distributed over a
lot of kilometers of the trajectory; the dust and gas in their basic
part may fly together with the comet and break off from it not so
fast as it may seem – taking account of all the forces and factors
(many of them though weak act in great scales) may lead to an unusual
result.
Note that the fact consisting in that one side
is more active than the other sub>stantially confirms the mechanism of
the comets formation as the result of punching the rings of the major
planets of the Solar system by asteroids (see the materials of the
application for the discovery), as far as the time of punching the
ring by an asteroid (<1 s) is not sufficient for the asteroid to
swing significantly. The porosity of coaly hondrites, for instance
(and as hondrites may serve asteroids and also, in particular, the
nucleus of the Halley-comet) may reach the value of more than 20%
[15], that may promote a significant adsorption and absorption of
volatile components which the ring contains. You should not forget
that the punching of the ring (the layer of small bodies of the
finite thickness and some average density) by a large asteroid is the
process of a successive interaction of a massive monolithic body of
irregular form with a great number of small bodies during a certain
time interval. In this case as the evaporation of the colliding
bodies is going on the shock wave will be growing “smoothly”
enough and exerting its influence for a long time. In general, the
physics of such an interaction differes from the physics of the
stroke of two solid bodies commensurable with each other and is of
interest as the object of a separate investigation both theoretical
and experimental. It is obvious, however, that this circumstance may
promote the capture of the volatile components of the ring.
And
now some remarks in respect of the photoes made by the “Vegas”
apparatuses. In [10] Academician R.Z.Sagdeyev says that:
“Powerful dust rejections are slightly camouflaging the
nucleus surface but a detailed photometrical treatment allowed to
determine its form, dimensions and reflecting ability”. However
there’s no statement that they succeeded is seeing the nucleus
surface itself. There’s no doubt that the averaging of images,
space filtering, etc., may “emphasize” something but they are not
able to “extract” the information that is absent in the
initial image. In this connection the statement that the images
of the comet nucleus proper were obtained is not quiet
correct. Incorrect and groundless is also the statement about that
“...in comets... the material of which the Solar system was
generated is preserved in its original form” [4]. Comets occur and
die nowadays with the probability which estimated the
above.
After the “Vega” experiment a number of new
hypotheses of the comet formation appeared, but they don’t resolve
all the contradiction in contrast to that offered by the
author. At present the major part of specialists suppose that
asteroids are dead comets (those left after the melting of ice - the
main component). This point of view is an intermediate one, as
far as it would be more correct to say: some asteroids are dead
comets (the main component of the comet mass is the asteroid
proper).
The basic arguments were formulated by the
author as far back as the beginning of 1985 and were expressed
in the letters, besides in 1986 they found their reflection in the
materials of the Application. At present these materials may be only
supplemented in the light of the new experimental facts and data.
The potent aspects of the hypothesis are:
-
its concrete character and the absence of any obstacles for the
further concretization; absence of any abstractions of the type comet
cloud of Oort, Nemesida, etc., that were seen by nobody;
- logical
inevitability of the offered mechanism, caused by the absence of
physical interdictions and the finite value of the probability of the
event;
- possibility of a versatile verification;
- logical
connection with all the available facts.
Besides, the
hypothesis at the same time gives a harmonious picture of such a
phenomenon as the “Tungus meteorite” (appendix to the
Application, here chapter 6), that in general agrees with new views
on this phenomenon [16] and removes any misticism and mystery,
created around this sensational question.
5. TERMINOLOGY AND
EXCEPTION TO THE RULE
If the term “comet”
implies a small celestial body with a gaseous cover (coma) or tail
consisting of gas and dust that is probably more concrete than a
vague meaning of this word given in dictionaries, then the author
proposes to call the comets formed as result of piercimg of the major
planets of the Solar system by asteroids to call these comets
“samaroid(s)” - in honour of the city of Samara which in 1986
celebrated its 400th anniversary (that was also the year of the
Halley-comet). As it follows from the introduction to this article
this name “samaroid” is quite justified.
For
the comets formed as a result of an asteroid passing along the
trajectory close to the tangent through the atmosphere of such
planets as the Earth, Mars and Venus (the Earth group) - it is known
at least one case when a bolide (fire-ball) entered the atmosphere of
the Earth, passed it through and then again went away beyond
the limits of the atmosphere and at this it didn’t become the Earth
satellite - the author proposes the name (or term) “novid”.
Though the probability of the formation of weak comets is such
a way is almost zero, still it should not be fully excluded out
of the sphere of our attention. After the contact with the atmosphere
any celestial body takes away with it a portion of gases. Even SA -
artificial Earth satellites have their own atmosphere. The term
“novid” descend from the name of a small and very picturesque
village “Novinky” situated in the Zhiguli mountains near the city
of Samara within the area of the first national park in Russia (not
1st in the USSR) “Samarskaya Luka”.
The two terms
proposed by the author symbolize the unity of great and small in the
Universe...
For the comets out of the cloud Oort (let
it be so! - the author is just enough) the author offers the term
“Oortides”. - Let the Time to prove the vitality of these
names.
Thus, the “cosmic bulldozer” - the
Halley-comet is, apparently, a ferrous-stony “samaroid” belonging
to the Neptune (or Uranus?) family.
6.
TUNGUS PHENOMENON
One of the arguments against the
proposed mechanism of the comet formation may be a false
interpretation of the event that took place in 1908 and is known
under the name “Tungus meteorite” as far as the zone of
fall was of an unusual character; the meteorite proper was not found.
In this connection a great number of hypotheses appeared on the
collision of the Earth and the icy comet that later on evaporated.
But as far as the comet is no more than a “dirty asteroid” and is
not a very original one as for the results of its influence then the
author offers the following non-contradictory explanation of
the event (without any pretension on originality).
At
8 o’clock a.m. on the 30th of June, 1908, in the Tungus taiga
the event took place known under the name of “Tungus meteorite”.
The examination of the place of the Tungus
meteorite fall in 1927 and later on showed the absence of the meteor
body and craters. The woods within the radius of 30 km was brought
down by the blast [17, p.54]. All these in total was unlike a usual
fall of meteorite.
Take notice of several
facts.
After the fall of Sihote-Alin meteorite in 1947
numerous splinters were found. On having analysed these splinters a
soviet scientist E.L.Krinov marked out conditionally three stages of
the meteorite splintering into composing parts by a number of
characteristic signs [17, p.42].
At the Tungus
meteorite fall an unusual phenomenon was observed: at the vast
territory to the west of the place of the meteorite fall the night
from the 30th of June to the 1st of July practically did not set in
[17, p.53]. The sky was light and even in England it was possible to
read a paper at this time (this phenomenon is, apparently, belonging
to the type of “crepuscular” ones as far as this season the Sun
sets not far beyond the horizon and the diffusion of Solar light may
occur in the upper layers on fine-dispersed particles). At the same
time to the east of the place of the meteorite fall there was nothing
of the kind. This circumstance sub>stantially confirms the assumption
that the trajectory of the Tungus meteorite fall was close to the
tangent to the Earth surface, i.e. the meteorite entered the
atmosphere of the Earth at the small angle to the horizon. At
such a trajectory the meteorite must move significantly longer in the
Earth atmosphere, experiencing at this its resistance and being
sub>jected to destruction. Thus, there are all the grounds to suppose
that the number of stages of destruction of the Tungus meteorite was
more than that of the Sihote-Alin meteorite (mentioned above) and on
approaching to the place of its fall the Tungus meteorite was almost
completely destroyed to small splinters, forming a kind of a cloud
consisting of stony hail or “rain” if the body was melted
in addition. On collision of this cloud with the Earth surface a
powerful blast must be generated over a great area and in fact this
phenomenon took place in case of the Tungus meteorite. Besides,
recently in the region of the explosion the microscopic balls were
discovered. These balls were not of the earthly nature [17,
p.55].
Thus, the Tungus meteorite is a small cosmic-body entered
the Earth atmosphere by the trajectory close to the tangent and
consequently sub>jected to the full destruction.
