Mercury, Venus, Earth, and Mars all have impact craters.
Mercury is the planet with the most visible craters in our solar system. Its surface is heavily pocked with impact craters due to its lack of atmosphere to protect it from incoming space debris.
All four inner planets have craters. Mercury is the most heavily cratered.
Each crater on Mercury was left behind by an asteroid or comet that collided with it. Many of the craters are nearly as old as the planet itself, as collisions were far more common when the solar system was young. Other craters may only be a few million years old.
