4179 Toutatis (1934 CT) is an elongated asteroid in the main asteroid belt, and is also a Mars and Earth crosser. It was first discovered on 10 February 1934, but was lost until is was again sighted on 4 January 1989 by Christian Pollas. It was named after a Celtic god.
Toutatis can approach Earth as close as 2.8 lunar distances, and approached as close as 4 LD in 2004. It has a 3:1 orbital resonance with Jupiter and near 1:4 resonance with Earth. This leads to a very chaotic behavior in its orbit which does not allow accurate predictions of its orbit far into the future. It has been classified as a potentially hazardous object.
Toutatis has been studied by radar a number of times and was visited by Chang'e 2 during a flyby on 13 December 2012.
Toutatis in Orbiter
4179 Toutatis was first introduced to Orbiter with the release of MainBeltAsteroids051403 in 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.
