Hielbentu (Planet)

Hielbentu is a planet located in the far orbit of Vela Pulsar, Sontar and Pistol Star. A day on Hielbentu is one Earth Hour and a year on Hielbentu is 88 Earth days. This planet only appears in few episodes in Uku Kivistik's Doctor Who show.The planet is a lot like Earth except no humans or animals can be found. It has Earth like atmosphere, rivers, plants and gravity just like Earth's. When the Doctor and Mark arrive on, there are no signs of life as they try to figure out how they are on the planet. Then they realize that the Sun became into a black hole 20 centuries ago. As the time passes by, Sontarans starts to appear around Vela Pulsar. Mark also mentions that one side of the pulsar was populated by humans due to terraforming glitch.

But then the stuff went south as the giant laser starts shooting at them.

The planet itself appears in few episodes, first appearance is in Hielbentu, a pun name made out of Hell Bent, a Doctor Who episode. Then the planet is seen in the same episode, after Axos has turned Earth into living hell. Other appearances are on posters and the fifth one is in End of the Line, the very final episode.
