Crater count

Crater count is a method used by scientists to determine the age of a planetary surface by counting the number and sizes of impact craters. Since planets and moons accumulate craters over time from space debris, a surface with more craters is generally older. By comparing crater density across different areas, scientists can estimate relative ages and build a timeline of geological history. This technique helps understand planetary evolution, surface processes, and the history of events like meteor impacts, providing insights into the planet’s past.
