What planet has many craters?

The planet with many craters is Mercury. Due to its lack of a substantial atmosphere, Mercury is unable to shield itself from asteroid and meteor impacts, resulting in a surface covered with numerous craters. Additionally, its proximity to the Sun means that it experiences extreme temperature variations, which can also affect surface conditions. The Moon also has many craters, but Mercury has the distinction of being the most cratered planet in the solar system relative to its size.
