Apollo asteroid

The Apollo asteroids are a group of near-Earth asteroids named after 1862 Apollo, the first asteroid of this group which was discovered by Karl Wilhelm Reinmuth. They are Earth-crosser asteroids that have orbital semi-major axes greater than that of the Earth (> 1 AU) but perihelion distances less than the Earth's aphelion distance (q < 1.017 AU).[1] Some can get very close to the Earth, making them a potential threat to our planet (the closer their semi-major axis is to Earth's, the less eccentricity is needed for the orbits to cross). The February 15, 2013 Chelyabinsk meteor that exploded over the town of Chelyabinsk in the southern Urals region of Russia, injuring an estimated one thousand people, breaking windows and destroying buildings, is thought to have been of the Apollo class of asteroids.[2][3]

The largest known Apollo asteroid is 1866 Sisyphus, with a diameter of about 10 km.
