List of craters on Mars: H-N
This is a list of craters on Mars. There are hundreds of thousands of impact crater on Mars, but only some of them have names. This list here only contains named Martian craters starting with the letter H – N ''(see also lists for A – G and O – Z)''.
Large Martian craters (greater than 60 km 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. Craters cannot be named for living people, and small crater names are not intended to be commemorative - that is, a small crater isn't actually named after a specific town on Earth, but rather its name comes at random from a pool of terrestrial place names, with some exceptions made for craters near landing sites.〔(Categories for Naming Features on Planets and Satellites ), Gazetteer of Planetary Nomenclature, USGS Astrogeology Science Center, NASA〕 Latitude and longitude are given as planetographic coordinates with west longitude.
