アテン群
, provisional designation , is a 970-meter asteroid and near-Earth object with the second smallest perihelion of any numbered asteroid (0.092 AU—38% of Mercury's orbital radius). With its high eccentricity, not only does get very close to the Sun, but it also travels relatively far away from it. It has the third largest aphelion of any numbered Aten asteroid and is one of a small group of Aten asteroids that is also a Mars grazer. Its orbital elements indicate that may be an extinct comet. It hasn't been seen displaying cometary activity so far.
