AI overview
An astronomical unit (AU) is the average distance between Earth and the Sun, which astronomers use as a standard measurement for distances within our solar system. This reference point makes it easier to describe and compare how far planets, asteroids, and other objects are from the Sun without using extremely large numbers.
