Nereus
4660 Nereus, provisional designation 1982 DB) is a small (about 0.33 kilometres asteroid. IIt was discovered by Eleanor F. Helin on February 28, 1982, approximately 1 month after a near pass by the Earth. Nereus is potentially a very important asteroid. It is an Apollo and Mars-crosser, with an orbit that frequently comes very close to Earth, and because of this it is exceptionally accessible to spacecraft. Indeed, because of its small size and close orbit, its delta-V for rendezvous of ~5 km/s is smaller than the Moon's, which is about 6.3 km/s. 4660 Nereus - Wikipedia, the free encyclopedia
