Oblivanus
From Tardis Wiki, the free Doctor Who reference
Oblivanus was a doughnut-shaped star in the Seventh Galaxy known as the "planet of destruction". Space craft venturing within a million miles of it would be drawn by its gravity and vanish in the star's hollow centre, in a process similar to a black hole.
The visible side of Skaro faced the region of the Seventh Galaxy containing Oblivanus. (PROSE: The Seventh Galaxy [+]Loading...["The Seventh Galaxy (feature)"])
