Asteroid 2201, diameter 2.8 km, discovered in 1947 by H. Giclas then lost until recovered in 1979. It is in a highly elliptical Earth-crossing orbit and has a unique spectrum that does not resemble that of any other known asteroid, meteorite or comet. Its nature is not known, but it could be the dead nucleus of a comet that has ceased to be active.
