Schaeberle is a crater in the Iapygia quadrangle of Mars, located at 24.7° S and 309.9° W. It measures approximately 159 kilometers in diameter and was named after John Martin Schaeberle, an American astronomer (1853–1924).[1]
Impact craters generally have a rim with ejecta around them, in contrast volcanic craters usually do not have a rim or ejecta deposits. As craters get larger (greater than 10 km in diameter) they usually have a central peak.[2] The peak is caused by a rebound of the crater floor following the impact.[3]
