7474 (1992 TC) is a moderate sized M-type asteroid discovered by Robert H. McNaught in 1992. It is notably one of a few similar M-type asteroids, including the named asteroids 4660 Nereus and 65803 Didymos, which can be reached easily by spacecraft from earth. The delta-V required to reach 7474 (1992 TC) would be about 5.6 km/s.[1], which is less than is needed to reach the moon. M-type asteroids are thought to be composed primarily of nickel and iron. If this is proven to be true, 7474 (1992 TC) may one day become an important source of raw materials in space.
