Constellation

A constellation was a group of stars.

Time Lords defined constellations as a group of stars based on their temporal and physical locations. They 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 concept, but had a different name for it. (PROSE: The Devil Goblins from Neptune)

In a vain plea to convince to leave the Earth, the Tenth Doctor offered to fight him "across the constellations". (TV: The Sound of Drums)
