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

Lockyer Crater 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.
