Why does mercury have more meteor and asteroids it its surface?

Mercury has more craters from meteors and asteroids on its surface due to its lack of a significant atmosphere, which means there is no protective barrier to burn up incoming space debris. Additionally, its proximity to the Sun places it in a region where gravitational influences can attract more objects, and its small size and low gravity make it less capable of retaining any potential atmosphere or geological processes that could erase impact craters over time. As a result, its surface remains largely unchanged, preserving a record of past impacts.
