The astronomical unit (au) is a unit of length used in astronomy.

One astronomical unit is roughly equal to the distance between Earth and the Sun.

The unit is used to measure distances at the scale of solar systems. For example, Jupiter is approximately 5 au from the Sun.

Definition of the astronomical unit

The astronomical unit is defined as exactly 149597870700 meters.

Some Facts

If the Sun were to be erased from reality, we would realise it 8 minutes and 20 seconds later, it is the time that light and gravity from the Sun take to reach us. During all that time, the Earth would continue on its orbit around an empty part of space as if nothing happened.

The International System of Units

The International System of Units or SI (from the French Système international (d'unité)), also called metric system in the U.S., is a coherent system of units that was published 1960. It is official in nearly every country.

The General Conference on Weights and Measures (Conférence générale des poids et mesures) is tasked with overseeing the SI.
