90 Antiopeis a double asteroid with S/2000 (90) 1 in the main asteroid belt between Mars and Jupiter, and was discovered on 1 October 1866 by Robert Luther. The name comes from Greek mythology. 90 Antiope was considered a single body until August 2000 when it was discovered to be two almost identical bodies, the mass differing by less than 2.5%. Antiope is now attributed to the larger body and the smaller body is desgnated as S/2000 (90) 1.

Antiope in Orbiter

90 Antiope was first introduced with the release of MainBeltAsteroids.zip in May 2003. Since Orbiter is not written for two bodies revolving about a gravity center, S/2000 (90) 1 is configured to revolve as a standard satellite about Antiope in this release.

Note that the landing surface as given in the config file is spherical, but the visual of these bodies are not, if you land, you will likely be above or below the visual surface.
