Geological Chronicle

Osiris is a tiny lunar volcanic crater measuring 0.96 kilometers across in the southeastern part of Mare Serenitatis. The feature lies to the northeast of the crater Dawes and to the west of the Montes Taurus range, west-southwest of the Apollo 17 landing site in the Taurus–Littrow valley.

Osiris and nearby Isis are located on conical uprises situated along a rille and are interpreted as small volcanic cones. Osiris is the largest of five cones on this rille.

The International Astronomical Union approved the crater name in 1976, adopting an Egyptian male first name.
