Sort

The first planets of the solar system and the closest to the sun, as Mercury occupies the eighth place among the planets in terms of size.

Surface

Mercury is a rocky planet, covering the surface of surface rock heart, a huge iron, interestingly, on this planet is its surface is full of Balfohat left by meteorites that hit him over the years, full of Mercury’s surface also Pintoouat many believed they were formed when the cold pulp warm the planet and has declined since about 4 billion years old, has led this process to inflate the planet’s surface.

The atmosphere

Atmosphere of Mercury is very thin almost non-existent, he got from the solar wind.
But because of the steep rise in the temperature of the planet – as well as its small size – the molecules of gas constituents of the atmosphere escapes to outer space because of the increased speed drop on the planet’s gravity, the opposite of what happens in the planetary Earth and Venus, where the atmosphere are unstable.

Temperatures

Temperatures on Mercury are very high but it is not stable, ranging between 90: 700 Kelvin, or about
-183: 427 degrees Celsius. And this difference is due to two things: first, the slow cycle of Mercury on its axis it completes it in 59 Earth days and, secondly, the lack of atmosphere or rather a rarity.

Disciples

There are no satellites orbiting the planet Mercury.
