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.
- Judging from the shadows, the craters Isis and Osiris have unusually raised rims compared to the other features in the area.
- The IAU Planetary Gazetteer attributes this name to a mythological figure, the Egyptian goddess Isis.
- Although derived from the name of a goddess, Isis actually appears to have been approved as a generic first name, honoring no person in particular.
- According to NASA RP-1097, "Isis" is a Minor Feature whose name was originally intended only for use in connection with Topophotomap 42C3/S1 (on which it is plotted).
- The name was approved, along with many other Topophotomap names, in IAU Transactions XVIIB (1979).
