This is an example list of Aten asteroids, a group of near-Earth asteroids. As of August 2015, there are 952 known Atens of which 169 received a final minor planet designation. Twelve of them received a name. Near-Earth asteroids are not numbered until they have been observed at two or more oppositions. (See also Aten asteroids (category) and Aten asteroid records.)

Named Atens

As of August 2015, a total of twelve Aten asteroids have received a name. They are listed in chronological order of discovery.

Brightest Atens

The following lists Aten asteroids thought to be larger than 2 kilometers across. Assuming an albedo of 0.15, this converts to an absolute magnitude of about 16.2
