Mary Blagg started the effort to standardize astronomical feature names in the early 1900s and today, the work is carried on by Tenille Gaither and Rosalyn Hayward of the USGS. Together, they manage the database incredibly known as the Gazetteer of Planetary Nomenclature.  The article is a great read about the history of naming features beyond Earth and the people who have kept everyone in sync. and then check out the Gazeteer’s website where you can browse all the named features, some of which feature great imagery like Pantheon Fossae on Mercury, the Baphyras Catena of Mars or a full maps of Uranian moons.
