Atira

From MIT.

The first asteroid ever discovered that has an orbit completely inside the Earth's, found by an MIT Lincoln Laboratory telescope in 2003 (with multiple exposures marked in red), has been formally named Atira by its discoverers. Seven more such inner-Earth orbit (IEO) asteroids have been found since, and the group is now classed as the Atiras. Courtesy / MIT Lincoln Laboratory
