2062 Aten (/ˈɑːtən/ AH-tən)[2] is an asteroid that was discovered at the Palomar Mountain Observatory by Eleanor F. Helin, who is now the principal scientist for the NEAT (Near-Earth Asteroid Tracking) project. It is named after Aten, the Egyptian god of the solar disk.

Aten was the first asteroid found to have a semi-major orbital axis of less than one astronomical unit. A new category of asteroids was thus created, the Atens. As of July 2004 about 16 Atens were numbered and some 212 were provisional,[3] the unnumbered Atens ranged from what was then 1989 VA to 2004 MD6.
