Eponym
Joseph N. Lockyer, British astronomer (1836-1920).

Lockyer is a crater in the Elysium quadrangle of Mars, located at 28° North and 199.5° West. It is 71 km in diameter and was named after Joseph N. Lockyer, a British astronomer (1836-1920).[1] Lockyer is fairly easy to spot on Mars maps because it sits in the relatively young northern hemisphere, where there are few craters. It is close to Elysium Mons and Hecates Tholus, two large volcanoes.


Phlegra Montes just north of the crater, a mountain range spanning over 1,350 km. Also there is one crater is located north-northeast, Adams.


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]
