243 Ida is a large asteroid shaped very elongated, perhaps a contact binary. It was discovered by Johann Palisa on 29 September 1884 and was named for a nurse of Zeus. On 17 February 1994, Ida was discovered to boast a small moon as it was imaged during the flyby of the Gallileo spacecraft in 1993 as it flew by enroute to Jupiter.
243 Ida in Orbiter
243 Ida and Dactyl were first introduced with the release of MainBeltAsteroids051403.zip in May 2003.
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. On the hard surface, Ida produces 99% of the gravity experienced by your ship and the Sun the other 1%. The acceleration due to gravity on the hard surface is about 0.0632 m/s2.
