Apollo asteroids are a group of near-Earth asteroids that have orbits that cross Earth's orbit. They are named after the first identified member of this group, 1862 Apollo, discovered in 1932. Apollo asteroids have semi-major axes greater than 1 astronomical unit (AU), which is the average distance from the Earth to the Sun, and they typically have eccentric orbits that bring them into close proximity to Earth.
