1620 Geographos is a Near-Earth object discovered in 1951 by Albert George Wilson and w:Rudolph Minkowski at Palomar and is named in honor of the w:National Geographic Society.

Geographos was to be visited by the w:Clementine mission, failed to reach the body.

Geographos in Orbiter

1620 Geographos was modeled in Orbiter as a soomewhat potato shaped object about 5 km on the longest dimension. Landing anywhere on the body's radius you end up well above the visual surface. Because even at the surface, geographos only provides 1% of the local gravity, the Sun providing the other 99%, a ship cannot orbit geographos, it can only fly along with it in solar orbit, maneuvering in its vicinity. A ship also cannot land and remain on the hard surface, it will immediately drift off the surface.
