Eponym	Hermann Joseph Muller and Carl H. Müller (German astronomer)

Müller is a 120.5 kilometer crater in the Martian southern hemisphere, at 25.74°S, 127.89°E, located in the Terra Cimmeria region of the Mare Tyrrhenum quadrangle of Mars. According to the International Astronomical Union's Working Group for Planetary System Nomenclature, Müller is jointly named for Hermann Joseph Muller, an American geneticist and anti-nuclear weapons activist, and Carl H. Müller, a German astronomer. Ejecta from the Müller crater divides two Noachian era drainage basins.

Muller 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. It's rim has probably been eroded away.
