Mons Hansteen
Mons Hansteen is a mountain on the Moon, also known as Hansteen Alpha (α), named after Christopher Hansteen. It is roughly triangular in shape and occupies an area about 30 km across on the western margin of Oceanus Procellarum, southeast of the crater Hansteen and north of the dark-floored crater Billy. It is thought to be an extrusion of volcanic material that is younger than the crater Hansteen.

with a thin inner wall. Only a few tiny craterlets mark the interior.
To the north of the crater is a triangular mountainous formation named Mons Hansteen, from the nearby crater. Southeast of Billy is a rille, designated Rima Billy, that runs 70 kilometers to the south.

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