Mission:

NEAR (Near Earth Asteroid Rendezvous) was a mission to rendezvous and orbit around an near earth asteroid (433 Eros). On the cruise to Eros, it flew by asteroid 253 Mathilde on 27 Jun 1997 and flew by earth on 23 January 1998. After failing to insert itself into Eros' orbit in January 1999, NEAR finally inserted itself into orbit around the asteroid on the second try on 14 February 2000. Initially in a 323 km × 370 km orbit, it lowered its altitude during observation. After reaching orbit, NEAR was renamed NEAR-Shoemaker.
