Astronomical Unit

An Astronomical unit (Au) is a unit of measurement of distance, frequently used to measure inter-planetary distances.

• It is an astrographic metric.

Description (Specifications)

One Astronomical unit (AU) is about 150 million kilometers (or, more precisely, 149¨597 870 691 ± 30 metres), or about 93 million miles.

History & Background (Dossier)

The Astronomical unit is derived from the average distance between the Terra and its Sun. Because the definition of a Parsec relies upon the Astronomical unit, the AU has become a standard unit of measurement within the Imperium.
