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 MainBeltAsteroids051403.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.

In the release of Antiope.zip by Bluefrog in January 2003, 90 Antiope and S2000 90 1 were modeled to orbit around a common gravity center by creating a ficticious body "Antiope" with the solar orbital parameters of the twin body system as given in the table to the right, but, the fictitious body has a radius of 4.25 meters, mass of 10.325×1016 kg, and was not given any visuals. 90 Antiope and S2000 90 1 were modeled as satellites of the fictitious body, orbiting each at 85000 km from Antiope each with the same mass, radius, and rotation periods.

Sol.cfg is listed like this, 'Planet5' being whatever planet number you assign in your file:
Planet5 = Antiope
Antiope:Moon1 = 90 Antiope
Antiope:Moon2 = S2000 90 1

NOTICE TO PILOTS: The Antiope center body is invisible, but has a hard surface 4.25 meters in radius. Do be very careful when flying between the bodies as not to crash into Antiope.

Note that the landing surface of 90 Antiope 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.
