summit: Surface of the Moon, photographed by Apollo 17, 13th December 1972.
Around 22°N 4°W in the Montes Apenninus, which form the southeast rim of the Mare Imbrium. Just below and right of centre is Mons Huygens, the tallest mountain on the Moon (5500m), and to the left is Mons Ampère. The small crater at top right is Huxley.
Mons Huygens is named for Christiaan Huygens (1629-1695); physicist, astronomer, and mathematician. A nearby crater on the Moon, another on Mars, an asteroid, and the Titan lander that accompanied Cassini to Saturn also bear his name.
Mons Ampère recalls André-Marie Ampère (1775-1836), the physicist and mathematician best remembered for his discoveries in electromagnetism. He lends his name to the SI base unit of current, often known as the amp.
Thomas Huxley (1825-1895) was a biologist, and an early advocate of evolutionary theory. He is said to have coined the term “agnostic”. Another crater, this one on Mars, is also named for him.
This detail is about 107km across.
