Mons Hadleyis amassifin the northern portion of theMontes Apenninus,a range in the northern hemisphere of theMoon.It has a height of 4.5 km (2.8 mi) 14,764 ft (4,500 m) above the adjacent plain and a maximum diameter of 25 km at the base.[1]

To the southwest of this mountain is avalleythat served as the landing site for theApollo 15expedition. To the southwest of this same valley is the slightly smallerMons Hadley Delta(δ) peak with a height of about 3.5 km above the valley floor. Mons Hadley Delta was visited and sampled by the astronauts, but Mons Hadley itself was only photographed from the surface. To the west of these peaks is the sinuous Rima Hadleyrille.

These features were named after the English mathematicianJohn Hadley.[3]

Rima Hadley[edit]

This sinuouslunarrillefollows a course generally to the northeast, toward the Mons Hadley peak, for which it is named. This feature is centered atselenographic coordinates25.0° N, 3.0° E, and lies within a diameter of 80 km. It begins at the crater Béla, an elongated formation with the long axis oriented to the northwest.

Satellite craters[edit]

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Mons Hadley.
