Why do active planets generally have fewer impacts than bodies like the moon?

Answer 1

It is not that active planets have less collisions than dormant planets or other astronomical bodies.The probability of an asteroid colliding with a celestial body does not depend on whether the planet has living beings on it or not. Infact, the earth gets hit by thousands of small asteroids everyday which get evaporated before they can reach the surface of the earth due to friction with the atmosphere.

Also in 1907, an asteroid collided near Siberia with 100 miles of area surroudning the collision point being completely flattened. The dinosaurs are believed to be gone extinct due to an asteroid collision. There are many sites where the asteroids have collided with Earth and left huge craters.

Answer 2

Active planets, like Earth, have geological processes such as erosion, tectonic activity, and atmospheric protection that constantly change their surface, making impact craters less common. In contrast, bodies like the Moon lack significant geological activity and protective atmospheres, resulting in a higher preservation of impact craters over time.

Answer 3

Actives planets likely only appear to have fewer impacts than moons. Active planets are able to absorb and cover up the damage.
