Tenten 10

From Tardis Wiki, the free Doctor Who reference

Tenten 10 was a planet in Mutter's Spiral. It was near the refuelling station on Hurala. It was often referred to as "the decimal planet". (PROSE: Prisoner of the Daleks)

Due to its proximity to Hurala, Klechton was likely located in the Lasron solar region in the Kappa Galanga sector.
