Harpalus T (Moon)

Satellite Feature of Harpalus

Named after Harpalus - Greek astronomer (unkn-c. 460 B.C.).

Harpalus is a young lunar impact crater that lies on the Mare Frigoris, at the eastern edge of the Sinus Roris. To the southeast at the edge of the mare is the small crater Foucault, and to the northwest on the opposite edge is the walled plain named South. The rim is sharp-edged with little sign of wear or erosion. The wall is not perfectly circular, and has a few outward notches and protrusions, especially along the eastern half. (wikipedia entry)
