Taurus–Littrow is a lunar valley located on the near side at the coordinates 20°00′N 31°00′E / 20.0°N 31.0°E. It served as the landing site for the American Apollo 17 mission in December 1972, the last manned mission to the Moon to date. The valley is located on the southeastern edge of Mare Serenitatis along a ring of mountains formed between 3.8 and 3.9 billion years ago when a large object impacted the Moon, forming Mare Serenitatis and pushing rock outward and upward. Taurus–Littrow is located in the Taurus mountain range and south of Littrow crater, features after which the valley received its name. The valley's name, coined by the Apollo 17 crew, was eventually approved by the International Astronomical Union in 1973.
