AS17-M-0597 This small area northeast of Dawes, on the border between Mare Serenitatis and Mare Tranquillitatis, is densely populated with minor feature names because it was plotted on two of NASA's high-resolution Topophotomaps. The upper group of Robert, Mary and Isis appears on 42C3/S1 and the lower group of Osiris, Catena Brigitte, Rima Marcello, Rima Reiko and Jerik is on 42C3/S2.

Osiris was also captured on Apollo 15's orbital panoramic ITEK-camera frames AS15-P-9560 and 9565. On these frames, Osiris is detectable near the lower right end of the rille-like (or chain-like) formation known as Catena Brigitte (which is the eye-catching "diagonal groove" in both frames) (north is to the right).

- Judging from the shadows, the small craters Osiris and Isis have unusually raised rims compared to other features in the area.
- The IAU Planetary Gazetteer attributes this name to a mythological figure, the Egyptian god of the dead Osiris.
- Although derived from the name of a god, Osiris actually appears to have been approved as a generic first name, honoring no person in particular.
- According to NASA RP-1097, "Osiris" is a Minor Feature whose name was originally intended only for use in connection with Topophotomap 42C3/S2 (on which it is plotted).
- The name was approved, along with many other Topophotomap names, in IAU Transactions XVIIB (1979).
