Lutetia

Lutetia (minor planet designation: 21 Lutetia) is a large M-type asteroid in the main asteroid belt. It measures about 100 kilometers in diameter (120 km along its major axis). It was discovered in 1852 by Hermann Goldschmidt, and is named after Lutetia, the Latin name of Paris.   Lutetia has an irregular shape and is heavily cratered, with the largest impact crater reaching 45 km in diameter. The surface is geologically heterogeneous and is intersected by a system of grooves and scarps, which are thought to be fractures. It has a high overall bulk density, suggesting that it is made of metal-rich rock.   Due to the high metal content Lutetia has been heavily mined. There are places to hide here. And places for others to hide too.
