MythologyMythology
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 characteristicsMain characteristicsMercury 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

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 MoonMercury and Moon
Mercury’s diameter is 40% larger than the MoonMercury, 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
