|Eponym||Percy B. Molesworth, a British astronomer (1867–1908)|
Molesworth Crater is a crater in the Aeolis quadrangle of Mars, located at 27.7° south latitude and 210.9° west longitude. It is 169 km in diameter and was named after Percy B. Molesworth, a British astronomer (1867–1908).
Molesworth Crater has a central peak. 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. The peak is caused by a rebound of the crater floor following the impact.
