Simpelius B (Moon)

Satellite Feature of Simpelius

Named after Sempill, Hugh Simpelius - Scottish mathematician (1596-1654).

Simpelius is an impact crater that lies in the southern part. It lies to the north-northwest of the somewhat larger crater Schomberger, and east-southeast of the prominent Moretus. The most distinctive aspect of this crater is the asymmetry of the inner wall, with the side being nearly twice as wide at the southern end as it is to the north. As a result, the level interior floor is offset to the north of the crater interior. (wikipedia entry)
