An astronomical unit (abbreviated AU) is a unit of measure on the interplanetary scale, roughly equal to the (average) distance between Earth and Sol. One astronomical unit is equal to 150 million kilometers, or approximately 93 million miles.

The map of the inner system of the Talosian system depicted the distance from the binary stars on a line. At every 10 intervals, there was a mark which represented one astronomical unit. The map showed that the inner system reached 3.4 astronomical units. (TOS: "The Cage")

The intense energy cloud created by V'ger was approximately 2 AU in diameter. (Star Trek: The Motion Picture)

The nucleogenic cloud being measured 7 AU in diameter. (VOY: "The Cloud")

When searching for Harry Kim in 2371, the USS Voyager performed a subspace scan with a scan radius of 10 AU. (VOY: "Emanations")

When Captain Sisko's runabout was approached by two Jem'Hadar attack ships in the Badlands in 2373, they initially were 1 AU away. (DS9: "Blaze of Glory")

In the original version of the film, V'ger's cloud was actually 82 AUs across. At their farthest point from each other (the aphelion), Earth and Pluto are just over 49 AUs apart. This would have made V'Ger's cloud almost twice that length, engulfing over half the solar system. As a result, the cloud size was toned down to a more reasonable number in the 2001 director's edition but even then, 2 AUs, the diameter of the Earth's orbit, is still an enormous size.

-An '''astronomical unit''' (abbreviated '''AU''') is a unit of measure on the interplanetary scale, roughly equal to the (average) distance between [[Earth]] and [[Sol]].  One astronomical unit is equal to 149,597,870,691 ±30 [[meter]]s, or approximately 150 million kilometers, or approximately 93 million miles.  Because interplanetary distances so quickly run up into the billions of miles or kilometers, (depending on which measurement system one uses), the AU is used to make these distance much easier to quantify in terms of easily discussing large distances throughout the solar system.  Upon leaving the solar system and discussing interstellar distances, the term AU fails and the [[light year]] or [[parsec]] is then brought in.
