Astra

Astra was a planet that was home to an Earth colony.

The colony was established at some point after the 23rd century. (AUDIO: The Suffering)

In 2493, Vicki and her father left Earth for Astra, but they never arrived. The ship they took crashed on Dido. (TV: The Rescue) Like many of Earth's colonies at the time, Astra was a terrible place. (PROSE: Christmas on a Rational Planet)
