Constellation

A constellation is a group of stars. At least two species had differing views of the concept of constellations.

Human Perspective
Humans defined constellations as a group of stars visible from the surface of a planet, usually named for the image they made when the stars were connected. Stars that made up a constellation were sometimes named after the constellation using the Greek alphabet (from Earth's point of view).


 * Alpha Centauri was a star of the Centaurus constellation.
 * Tau Ceti was a star of the Cetus constellation.

Time Lord Perspective
Time Lords defined constellations as a group of stars based on their temporal and physical locations. It also included stars that hadn't been created yet and stars that had died out. This concept was later used in Humanity's distant future. The Kagananaga Botizoids had a similar theory, but had a different name for it. (PDA: The Devil Goblins from Neptune)
