* Crater Count: We can see countless craters on the Moon's surface, but many are extremely small and difficult to distinguish.
* Erosion and Impact Over Time: The Moon's surface has been bombarded for billions of years. Erosion from micrometeorites and solar wind wears away craters, and new impacts are constantly happening.
* No Atmosphere: Unlike Earth, the Moon lacks an atmosphere to burn up smaller asteroids before they reach the surface.
However, we can make some estimates:
* Large Impacts: Scientists estimate that about 185 large craters with diameters greater than 20 km have been formed on the Moon's near side.
* Small Impacts: It's thought that hundreds of thousands, if not millions of smaller impacts occur on the Moon each year.
Important Note: While the Moon is bombarded frequently, the vast majority of impacts are from small particles, posing no threat to humans.
