This is a list of craters on Mars. Impact craters on Mars larger than 1 km (0.62 mi) exist by the hundreds of thousands, but only about one thousand of them have names. [ 1 ] Names are assigned by the International Astronomical Union after petitioning by relevant scientists, and in general, only craters that have a significant research interest ...
This list here contains only named Martian craters starting with the letter O – Z (see also lists for A – G and H – N). Large Martian craters (greater than 60 kilometers in diameter) are named after famous scientists and science fiction authors; smaller ones (less than 60 km in diameter) get their names from towns on Earth.

Following are the largest impact craters on various worlds of the Solar System. For a full list of named craters, see List of craters in the Solar System. The ratio column compares the crater diameter with the diameter of the impacted celestial body. The maximum crater diameter is 157% of the body diameter (the circumference along a great circle).
The system spotted the craters by scanning photos by NASA’s Mars Reconnaissance Orbiter, which was launched in 2005 to study the history of water on the red planet.
The common surface features of Mars include dark slope streaks, dust devil tracks, sand dunes, Medusae Fossae Formation, fretted terrain, layers, gullies, glaciers, scalloped topography, chaos terrain, possible ancient rivers, pedestal craters, brain terrain, and ring mold craters.
Huygens is an impact crater on Mars named in honour of the Dutch astronomer, mathematician and physicist Christiaan Huygens.It is the fifth largest recognizable impact crater on Mars after Utopia, Hellas, Argyre, and Isidis, and the largest one with a near intact rim.
An expanded crater is a type of secondary impact crater. [22] Large impacts often create swarms of small secondary craters from the debris that is blasted out as a consequence of the impact. [22] Studies of a type of secondary craters, called expanded craters, have given us insights into places where abundant ice may be present in the ground.
