Impact craters

Impact craters

The impact craters they are circular or elliptical depressions in the solid crust of the planets, caused by the impact of celestial bodies such as asteroids, comets and meteorites.

All the bodies of the solar system characterized by a solid crust (the planets Mercury, Venus, Earth, Mars and many natural satellites of these), have been intensely bombarded by the bodies mentioned in the first phases of formation of the solar system.

In all the celestial bodies lacking a consistent atmosphere and active geological processes, the signs of the craters have remained immutable even when billions of years have passed. On Earth and on the other planets endowed with a rich and geologically active atmosphere, the complex of dynamic phenomena has eroded and erased most of these ancient scars.
