astronomical unit (AU)
= 149,597,870.691 km; the average distance from the Earth to the Sun. 1 AU is a long way -- at 100 miles per hour (160 kph) it would take over 100 years to go 1 AU.

Several scientific and computing uses come to mind:
Astronomical unit (AU, au, a.u., or ua), a unit of length approximately equal to the distance between the Earth and the Sun
Atomic units (au), a system of measurement units based on fundamental atomic properties
The chemical symbol of Gold (Au)

Astronomical unit = mean distance from Earth to sun
Used for local space measure - not good for stars and beyond, as the nearest stars are millions of AU.
