Apollo asteroid

Also known as Apollo objects, Apollo-class asteroid

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)

AI overview

Apollo asteroids are a group of space rocks that cross Earth's orbital path, with orbits that extend farther from the Sun than Earth's but come closer to the Sun than Earth's farthest point. They matter because their Earth-crossing trajectories make them important to monitor for potential collision risks and to study for understanding our solar system.

Common orbital subgroups of Near-Earth Objects (NEOs)

The Apollo asteroids are a group of near-Earth asteroids named after 1862 Apollo, discovered by German astronomer Karl Reinmuth in the 1930s. They are Earth-crossing asteroids that have an orbital semi-major axis greater than that of the Earth (a > 1 AU) but perihelion distances less than the Earth's aphelion distance (q < 1.017 AU).
