Mont Blanc is a mountain in the Montes Alpes range on the Moon. It is located on the western edge of the range, near the shore of Mare Imbrium, at [ ⚑ ] 45°29′N 0°25′E / 45.48°N 0.42°E. Its width is about 25 kilometers; the height is 3.7–3.8 km above adjacent plains of Mare Imbrium and 1.12 km above lunar level of zero elevation (a sphere with radius 1737.4 km).[1]
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]
