Theta Zeta

Theta Zeta was the designation for an uncatalogued class Y planet or planetoid located near the center of the Verubin Nebula.
It had the unfortunate distinction of being ground zero for the Burn in 3069. Ironically, when it was re-discovered a century later, its abundance of dilithium was crucial in allowing the to recover.
== Planetary features ==
Theta Zeta's environment was extremely harsh, bombarded by lethal radiation consisting of two types of theta radiation, delta radiation, electromagnetic radiation, subspace radiation, and two hitherto unknown forms of radiation.
Its surface was marked by massive concavities and it was orbited by chains of numerous small asteroidal bodies. It had large quantities of dilithium and was identified with a dilithium nursery. ()
== History ==
In 3064, the , a Kelpien research vessel, crashed on Theta Zeta while investigating the dilithium nursery. Five years later, Su'Kal, a child born to Dr. Issa among the wreckage, witnessed the death of his mother by radiation poisoning and screamed in horror. Because his genes had mutated to interact with dilithium in unique ways, and dilithium had a subspace component, this scream unleashed the Burn across the galaxy without his knowledge. ()
In 3189, the Federation starship tracked the source of the Burn to Theta Zeta. Cleveland Booker was able to identify a pocket within the Verubin Nebula near the planet for Discovery to spore-jump to in an attempt to investigate the crash site of the Khi'eth, apparently the only structure on the planet/planetoid. When Captain Saru, Commander Michael Burnham, and Doctor Hugh Culber transported to the ship, they found the sole life sign to be Su'Kal, still alive and living in a holographic simulation. Saru, Culber, and Adira Tal stayed behind on the Khi'eth to attempt to reach Su'Kal while Burnham returned to Discovery with Booker to retake the starship from Osyraa and the Emerald Chain. ()
Eager to mine dilithium from Theta Zeta, Osyraa tried to torture the planet's location within the nebula out of Booker, but Burnham rescued him before Osyraa could break him. After Discovery was re-taken, the vessel jumped back to Theta Zeta and rescued the away team and Su'Kal moments before the Khi'eths remains finally fell apart.
In the aftermath, the Federation figured out how to safely mine Theta Zeta, and began distributing its dilithium to resource-starved worlds across the galaxy. ()

===Background information===
 It was described there as a "planet/planetoid", although in dialogue it was consistently referred to as a planet. Digital artist Timothy Peel referred to Theta Zeta as "the dilithium planet," noting on Twitter that it was "a complex planet to render and animate!" 
In , Owosekun says that the Khi'eth crash site on Theta Zeta is located "two hundred kilometers into the nebula." Given the apparent size of the Verubin Nebula – large enough to make locating the planet difficult for Osyraa in – this comment should perhaps not be taken at face value.
