Near Earth Asteroid Rendezvous

The Near Earth Asteroid Rendezvous (NEAR) is the first to ever orbit an asteroid. It was launched in 1996. NEAR started to orbit Eros on February 14, 2000.

The goals of the mission are to learn as much about asteroids as possible. Instruments on the probe will analyze the makeup of Eros, take pictures of it, and look for a magnetic field.

Eros is one of the largest asteroids near Earth. It was discovered in 1898.
