Apollo asteroids
family of Earth-crossing asteroids that have an orbital semi-major axis greater than that of the Earth (a > 1 AU) but a perihelion distance less than the Earth's aphelion distance (q < 1.017 AU)
The Apollo asteroids are a group of asteroids near Earth named after 1862 Apollo, the first asteroid of this group to be discovered by Karl Wilhelm Reinmuth. They are asteroids that cross Earth. Some of these asteroids can get very close to the Earth, making them a potential threat to our planet.
