New Names on Mars

14 September 2006

Five new names have been approved for Mars: Angustus Labyrinthus, Chronius Mons, Promethei Mons, Sisyphi Tholus, and Thyles Montes. The names Australis Patera, Angusta Patera, and Cavi Frigores have been marked as dropped in the database. New imagery has shown that the two paterae were named using the wrong descriptor term, and the area previously named Cavi Frigores has been incorporated into the adjacent Cavi Angusti.

The definition of the descriptor term labyrinthus has been expanded from "Complex of intersecting valleys" to "Complex of intersecting valleys or ridges."

See the Gazetteer of Planetary Nomenclature for more information.
