Satellite

Artificial satellites are constructed objects sent into planetary orbit for one reason or another.

During 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) Earth now has about 5000 satellites which included 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 the satellites were turned off. (DW: The End of the World)
