Keeler is an impact crater on Mars, located at 61.0°S latitude and 151.3°W longitude in the Phaethontis quadrangle. It is 95.0 km in diameter and was named after James Edward Keeler, and the name was approved in 1973.[1] The first image below shows the relationship among three craters that are near each other. Keeler Crater is to the North of Trumpler Crater. After Keeler was formed, a later impact formed Trumpler Crater, and in the process destroyed part of Keeler. See also
