Müller is a 120.5 kilometer crater in the Martian southern hemisphere, at 25.74°S, 127.89°E,[1][2] located in the Terra Cimmeria region of the Mare Tyrrhenum quadrangle of Mars.[3] 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.[1] Ejecta from the Müller crater divides two Noachian era drainage basins.[4]

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.[5] The peak is caused by a rebound of the crater floor following the impact.[6] Its rim has probably been eroded away.
