Ceti Alpha VI

Ceti Alpha VI was the uninhabited sixth planet of the Ceti Alpha system. This system was located in Sector 25712 of the Alpha Quadrant. It was located a considerable distance from the Delphic Expanse and the planet Denobula as well as three days away from Regula I at an unspecified warp speed. The nearest starbase was Starbase 12. (; ; )
The planet exploded for reasons unknown in 2267, approximately six months after Khan Noonien Singh and his followers were exiled on Ceti Alpha V. The shock of the explosion shifted the orbit of Ceti Alpha V, destroying that planet's ecosystem, making the planet virtually uninhabitable. 
In 2285, the arrived in the Ceti Alpha system to find a suitable planet for testing of the Genesis Device. Believing that the planet was Ceti Alpha VI, Pavel Chekov and Captain Clark Terrell personally beamed down to its sister world, Ceti Alpha V, to confirm a scant detection of possible lifeforms. On the harsh, desert surface, they found a ramshackle shelter made up of several cargo containers, the inhabitants missing. As they explored the containers, Chekov, looking closely at a nearby strap buckle, saw the name SS Botany Bay stamped on it and realized to his horror that the containers belonged to the exiled augment, Khan. Urging his captain to follow him outside, the two were captured by Khan himself and the remnants of his crew. ()
In an alternate timeline, Human refugees fled to the Ceti Alpha system, following the Xindi's successful destruction of Earth in February 2154, during the relentless pursuit of the Xindi to eradicate all Human colonies. ()

=== Background information ===
This planet's quadrant of origin is inferred based on the position of Starbase 12, the closest starbase, as seen in the star chart appearing in the episode .
=== Apocrypha ===
In Greg Coxs To Reign in Hell: The Exile of Khan Noonien Singh, Spock theorizes that a small black hole might have passed through the system, too small to be detected easily by the sensors aboard the , and that its immense gravity destroyed Ceti Alpha VI and fundamentally altered the orbit of Ceti Alpha V.
The Star Trek: Vanguard novel Storming Heaven sets out that its destruction is inadvertently caused by Starfleet use of technology.
