Geological Chronicle
Mons Huygens is the highest mountain in the Moon's Montes Apenninus range, with Mons Ampère adjacent to the west. Altimetry data from the Lunar Reconnaissance Orbiter shows that the mountain rises 5,300 meters from its Mare Imbrium base. The surrounding Montes Apenninus range was formed by the impact that created Mare Imbrium.
The feature spans a diameter of 41.97 kilometers and was named after Christiaan Huygens, the Dutch astronomer, mathematician, and physician who discovered Saturn's largest moon, Titan. Mons Huygens has often been mistakenly cited as the Moon's tallest mountain and compared with Mount Everest, giving the incorrect impression that the Moon's tallest mountain is only a little more than half the height of Earth's tallest above sea level.
