The major impacts that form large craters are rare events, occurring on Earth roughly every 100 million years. The last major impact was 65 million years ago (mya). Over such a long period of time, the forces of erosion, deposition, and plate tectonics can destroy or bury a crater. The remnants of the 65 mya impact crater, for example, are buried under more than a kilometer of sedimentary rock. Large impacts were more common when the solar system was young and many of the large craters on the moon date to that time, but almost none of Earth's crust from that time still exists.

Large craters are not as common on Earth compared to other celestial bodies like the Moon because Earth has an active geology that constantly reshapes its surface through processes such as erosion, tectonic activity, and volcanic eruptions. Additionally, Earth's atmosphere serves as a protective barrier that helps prevent large celestial objects from impacting the surface. Lastly, many large craters that may have existed in the past have been eroded or covered over time.
