Satellite
- This page concerns artificial satellites. For natural satellites, see moon.
Satellites are constructed objects sent into planetary orbit for various reasons.
In the 1950s, the early age of satellites on Earth, the Soviet Union "space dog" Laika was sent into Earth orbit and died in a satellite. (EDA: Alien Bodies) By 2009, Earth had about 5000 satellites, including the Archangel Network and possibly the Guinevere satellites. (DW: The Sound of Drums/Last of the Time Lords, Turn Left)
By 200,000 Earth had five moons, four possibly being artificial and possibly including Satellite Five, which was a space station despite its name. (DW: The Long Game)
Up until 5,000,000,000 the National Trust had used gravity satellites to hold back sol's expansion, but when money ran out they were turned off. (DW: The End of the World)
