Smallest Planet

the smallest planet in our solar system
what is the smallest planet? Solar planets are a
fantastic mixture of what is possible with regard
to the creation of planets. From the solar
system there are terrestrial planets - bodies
consisting mainly of silicate minerals and
alloys. And in the external solar system, you
have gas giants and organizations consisting
mainly of ice, which is located a little further
in the Trans-Neptune area.
The question is what will be the smallest planet
ever controversial. Until recently, Pluto was
considered the smallest planet. But, using the
entire IAC Resolution of 2006, which imposes
restrictions on what the definition of this
planet includes, this status has since passed
into Mercury. Size and volume With an average
radius of 2,440 km, Mercury is the smallest
planet in our solar system, the size of 0.38
Earth. And, assuming that he does not encounter
flattening at the poles - for example, on Venus,
this means that it is an almost perfectly curved
body - its radius at the poles is exactly the
same as at the equator. And although it is
smaller than the most significant natural
satellites in our solar system, such as Ganymede
and Titan, it is more massive. The mass is 3.3011
1023 pounds (33 trillion metric tons 36.3
trillion US tons), which is equal to 0.055 Earth
relative to the mass. Because of this, gravity is
3.7 m / s2, which may be 0.38 times greater than
that of the Earth (0.38 g). Necessarily this
means that if you can stand on the surface of
Mercury, you will weigh 38 percent more than on
Earth. In terms of volume, Mercury again becomes
a little diminishing, at least by earthly
standards. In fact, Mercury has a volume of 6.083
1010 km3 (60 billion cubic kilometers 14.39
billion cubic kilometers), which will be 0.056
times the volume of the Earth. In other words,
you can place Mercury on Earth almost twenty
times.

Structure and composition Like Earth, Venus and
Mars, Mercury is an earth planet, which means
that it is mainly composed of silicate minerals
and compounds that differ between the metal core
and silicate mantle, as well as the earth's
crust.
Ho wever, in the case of Mercury, the core is
too large compared to other planets on the
planet, its radius is approximately 1800
kilometers (approximately 1118.5 kilometers), and
therefore it occupies 42 percent of the volume
of this planet (compared to 17 percent).
land). To describe this, many theories have been
proposed, the most widely recognized of which is
that Mercury was the largest planet that
collapsed planetesimally, which tore apart most
of the first crust and mantle, leaving the core
as the most important element. Under the core,
there are mantles 500700 km thick (310435 km),
consisting mainly of silicate material. The
surface of the Mercury crust, which consists of
silicate material with a depth of 100-300
kilometers. Yes, Mercury is a rather small client
compared to its brothers, brothers and distant
relatives in the solar system. But he is also
one of the most dense, hot and irradiated. Thus,
being humble, no one ever ascribes to this
planet, because it is very fashionable,
