Temporal orbit

A temporal orbit was a manoeuvre involving a TARDIS travelling back over its own time stream and holding in orbit over a single temporal location. This manoeuvre was used by the Eighth Doctor in his TARDIS (though Grace Holloway was at the controls) to reverse the effects of the Eye of Harmony on Earth in 1999. (TV: Doctor Who)

The Eighth Doctor also used a temporal orbit to develop a cure for Janusian radiation sickness after Samantha Jones had died from it, in order to be able to return prior to her death and save her. (PROSE: The Janus Conjunction)

The TARDIS once forced itself into a temporal orbit every time the Doctor tried to leave Earth. (PROSE: Autumn Mist)

The Eighth Doctor entered a temporal orbit in order to give himself enough time to read and transcribe The Darvias Saga. (PROSE: Best Seller)

The Eighth Doctor was trapped in a temporal orbit when the TARDIS stalled after taking a bout of temporal turbulence during the Last Great Time War. (PROSE: Ghost of Christmas Past)

The War Doctor "parked" his TARDIS in a temporal orbit while preparing the possibility engine to employ in the Tantalus Eye, against the Daleks. (PROSE: Engines of War)

In one account, the maneuvre which allowed Professor Chronotis to come back to life after his mind was stolen by Skagra involved a temporal orbit. (PROSE: Shada)
