The Sun

Sol or the Sun was the home star of the Sol System, a planetary system about twenty-seven thousand light years from the galactic center of Mutter's Spiral.

Historical overview

 * Life evolved on at least X natural satellites orbiting Sol: Venus, the twin planets of Earth and Mondas, Mars and the Fifth Planet.


 * At an early stage of development, Venus supported native sentient life. (MA: Venusian Lullaby)


 * Circa 9,000,000 BCE Time Lords placed the Fifth Planet in a time loop, in effect, destroying it. One of the Fendhal, which came from the Fifth Planet and which the Time Lords had meant to destroy, possibly destroyed life on Mars, though it certainly did visit Earth. (DW: Image of the Fendhal).


 * An asteroid belt somehow resulted from the time looping of Fifth Planet. Perhaps the Time Lords themselves imported the asteroids as replacement for the excess mass missing when they mae the Fifth Planet dissapear.''


 * Sometime before 4000 CE, Mavic Chen assumed the position of Guardian of the Solar System. Chen's secret allies, the Daleks at the same time proposed to conquer the Sol system. (DW: Mission to the Unknown, The Daleks' Master Plan)


 * Human scientists predicted solar flare activity would sterilize their homeworld, Earth and took measures to prepare. (DW: The Ark in Space)


 * Circa 2,000,000, the Time Lords transported the entire solar system using a magnetron. (DW: ''The Mysterious Planet).


 * In some unknown way, the move once more devastated Earth, which less informed people attributed to solar flares.


 * Eventually, Earth collided with its sun. (DW: The Ark, Frontios, DW: The End of the World).


 * Different sources disagree with the date of the death of Earth, varying describing it as circa 10,000,000 CE (DW: The Ark) in the 57th Segment of Time or circa 5,000,000,000 CE, or (using the then-contemporary dating system) 5.5/Apple/26.

Comings and goings

 * During the time of the Silurians and Sea Devils, a rogue planet approached the orbit of their homeworld, Earth. (DW: Doctor Who and the Silurians)


 * We do not know whether or not this planetoid originated from outside the Sol system.


 * Originally orbiting Sol at the same distance as Earth, Mondas left orbit and wandered out further into the Sol system. (DW: The Tenth Planet)


 * The planetoid or moon Voga entered the solar system sometime after the construction of the Nerva Beacon. (DW: Revenge of the Cybermen)


 * Circa 5000, the Doctor destroyed Saturn's moon, Titan. (DW: ''The Invisible Enemy)

Cultural and religous significance

 * In 100,000 BC a tribe of early humans worshipped Sol as Orb. (DW: An Unearthly Child).


 * In Mexico circa the 15th century, the timing of a solar eclipse had great religious significance. (DW: The Aztecs)
