Oblivanus
From Tardis Wiki, the free Doctor Who reference
Oblivanus was a planet 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 planet's hollow centre.
The visible side of Skaro faced the region of the Seventh Galaxy containing Oblivanus. (PROSE: The Seventh Galaxy [+]Loading...["The Seventh Galaxy (feature)"])
