Mythology
  • In Roman mythology Mercury is the god of
    commerce, travel and thievery, the Roman
    counterpart of the Greek god Hermes, the
    messenger of the Gods.
  • The planet probably received this name because it
    moves so quickly across the sky.
  • He was seen as the god of the twilight or of the
    wind.

Main characteristics
Mercury is the closest planet to the sun. The
orbit, or path, it takes around the sun is not in
a circle like Earth. The path it takes is called
an ellipse, which is like a circle that has been
stretched out. For this reason, the distance from
Mercury to the Sun varies from about 27 million
miles at its closest, to about 41 million miles
at its furthest.Mercury races around the Sun
faster than any other planet. A Mercurian year
(the time it takes for the planet to go once
around the Sun), is only 88 Earth days
Mercury is about a third of the size of Earth,
yet its density is comparable to that of Earth.
This indicates that Mercury has a large core
roughly the size of Earth's moon or about 75 of
the planet's radius. The core is likely composed
of radius. 60 to 70 iron by mass
Temperature variations on Mercury are the most
extreme in the solar system ranging from 90 K to
700 K

Get information about
Mariner 10 eventually made three flybys of
Mercury from 1974 to 1975 before running out of
attitude control gas. The probe revealed Mercury
as a heavily cratered world with a mass much
greater than thought.

Mercury and Moon
Mercurys diameter is 40 larger than the
Moon Mercury, like Moon is pocked with craters,
contains hugh multi-ring basins, and many lava
flows. The craters range in size from 100 meters
(the smallest resolvable feature on Mariner 10
images) to 1,300 kilometers.
Mercury never received the visit of a Man
