What is the Astronomical Unit?

The astronomical unit is a unit of length and is used in the Astronomical system of units and denoted by the symbol au.

It represents the average distance between the Earth and the Sun which is approximately 150 million kilometres (or 93 million miles).

It's used mostly to express distances within our Solar System.

Kilometre
