NASA’s NEAR Shoemaker spacecraft visited asteroid 433 Eros in 2000. It entered orbit around Eros on February 14, 2000, becoming the first spacecraft to orbit an asteroid.
NEAR stood for Near Earth Asteroid Rendezvous. Launched in 1996, the spacecraft first flew past asteroid Mathilde before using an Earth gravity assist to reach Eros. Eros is an elongated, heavily cratered near-Earth asteroid about 17 kilometers long and was discovered in 1898.
The mission was renamed NEAR Shoemaker in honor of planetary geologist Eugene Shoemaker. After studying Eros from orbit for about a year, the spacecraft made the first successful landing on an asteroid on February 12, 2001. It survived the landing and returned additional data for roughly two weeks.
The other choices belong to different missions or categories: Bennu was visited and sampled by OSIRIS-REx, Vesta was orbited by Dawn, and Itokawa was visited by Japan’s Hayabusa.
