Satellites were constructed objects sent into planetary orbit for various reasons.

The Third Doctor and Sarah Jane Smith buried Laika on Quiescia. (PROSE: Alien Bodies) According to another account, Laika was rescued by an alien entity and given human level intelligence and human voice (taken from cosmonaut Marinka Talanov). The Sixth Doctor and Peri Brown encountered her on 10 November 1963. (AUDIO: 1963: The Space Race)
