The Moon

The Moon is the nearest celestial body to the Earth, it is about 400 thousand kilometres away, or rather 800 million footsteps. It is the only body, up to now, that has been partially explored by man.

The Moon’s appearance, as the figure clearly shows, is proof of the great importance of the meteoric crashes in our Solar System’s past. Its surface is covered in a myriad of craters which are circular structures 30-40 kilometres wide with a flat base and raised edges.

The craters on the Lunar surface are the result of collisions with meteorites, or perhaps, although it is very unlikely, of volcanic phenomena. The impact of the collisions, on the Moon and on the other Satellites, was particularly violent because the meteorites were not blocked by the friction of an atmosphere. There are still collisions even today but not so many as in the past.

The origin of our satellite is still not completely known. According to the most accredited theory, a gigantic impact on the terrestrial surface caused material from its core to spill out; which then condensed to form the Moon.
