New Name for Towering Lunar Mountain Approved
The Working Group for Planetary System Nomenclature of the International Astronomical Union (IAU) has approved an official name for a mesa-like lunar mountain that towers above the landscape carved by craters near the Moon’s south pole. This unique feature will now be referred to as Mons Mouton, after NASA mathematician and computer programmer Melba Roy Mouton (MOO-tawn).
