Byrgius R (Moon)

Satellite Feature of Byrgius

Named after Burgi, Joost Byrgius - Swiss horologist (1552-1632).

Byrgius is a lunar crater located near the limb. As a result, Byrgius appears strongly oval in form due to foreshortening. To the northwest is the nearly ruined crater Lamarck. The rim is worn and eroded, with Byrgius A overlying the eastern rim and Byrgius D lying across the northwest. (wikipedia entry)
