The surface of Mercury is quite similar to that of the Moon. It is covered with craters, mountain ranges, faults and plains areas. In the image taken by the Mariner 10 space probe, Mercury craters can be seen perfectly. They are of various sizes, ranging between 100 meters and 1,300 kilometers in circumference. The Caloris crater is the largest on the entire planet, and is believed to have been formed by the impact of a large meteorite.
Many of the mountains of Mercury have a rounded appearance and are covered with dust. Its erosion is also due to the constant bombardment of meteorites. As for the faults, they rise several kilometers high, and have a length of hundreds of kilometers.
Mercury volcanoes have not yet been identified, but it is known that the flat areas of the planet have been repeatedly covered by melted material. Along the planet you can also see some steep mountain ranges. Its presence suggests that, in the past, Mercury suffered a cooling and contracted, causing the surface to rise.
From the surface of Mercury the Sun seems two and a half times larger than seen from Earth. But, unlike our planet, the sky always looks black, because the atmosphere of this small planet is insufficient to cause the scattering of light.
