Here, have a poor-rez screenshot from The End of Time that implies Jupiter and Saturn can be seen this close together and this clearly.

The Solah Systum is a patch of space around the sun filled with loads of planets and eggs moons and things, where Earth resides and houses its devil spawn. It's 99.99999999% the main setting of Doctor Who.

Planets Edit

The sun is orbited by a few giant orb-like things called planets.

Trivia Edit

If it wasn't obvious, the Doctor Who version of the Solar System has way more planets than its real life counterpart.

Mavic Chen was GUARDIAN OF THE SOLAR SYSTEM in the 4000s.
