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[edit]

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

The February 15, 2013 Earth encounter shortened 367943 Duende orbital period to about 317 days, changing its orbital class from Apollo to Aten.[1]

Brightest Atens[edit]

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
