Tombaugh Crater is an impact crater in the Elysium quadrangle of Mars, located at 3.5°N latitude and 198.2°W longitude. It is 60.3  km in diameter and was named after Clyde Tombaugh, American astronomer (1906–1997), and the name was approved in 2006 by the International Astronomical Union (IAU) Working Group for Planetary System Nomenclature (WGPSN).[1]

Why craters are important

The density of impact craters is used to determine the surface ages of Mars and other solar system bodies.[2] The older the surface, the more craters present. Crater shapes can reveal the presence of ground ice.
