Asteroid impact on Mars

Asteroid impact on Mars

Some solar planets are bombarded with asteroids very hard in the past and Mercury is one of them. It has 700 km wide impact still seen from Earth.

Every planet in solar system is spinning in the same direction except Venus. Because Venus is heat by asteroid so hard, that it spins the wrong way.

Mars has largest crater in solar system created by asteroid impact. The crater is so huge that it can only be seen from space.
