Location of Mont Blanc in lunar Alps

The name of Mont Blanc, the highest mountain of terrestrial Alps, was proposed for this mountain by Johann Hieronymus Schröter.^[2] It was approved by International Astronomical Union in 1935.^[2][3] It is the only summit of Montes Alpes with proper name and the only extraterrestrial mountain, whose international name contains French word "Mont" instead of Latin "Mons".^[4]

Despite statements that lunar Mont Blanc, like terrestrial one, is a highest mountain of its Alps,^[5] measurements of Lunar Reconnaissance Orbiter show that it is only third, being 600 meters lower than the highest one and about 100 m lower than the second.^[1]
