As evidence of a "hidden and giant" planet on the edge of the solar system emerges, we want to know what name you would give it.

Scientists discovered "Planet Nine" using computer simulations - and the new addition is thought to be about 10 times more massive than Earth, and similar to Uranus or Neptune in its make-up.

But what name would you pick for it?
We've had a bit of fun in the newsroom today thinking of new names for our solar system's latest find, from North East-inspired titles to popular culture references.
The new world, which is yet to be observed directly by astronomers, is described as a "true planet" with 5,000 times the mass of Pluto, which was re-classified as a minor or "dwarf" planet.

The latest discovery is believed to trace a highly elongated orbit, with it taking between 10,000 and 20.000 years to make one journey around the sun - being 20 times further away from it than Neptune.

Professor Mike Brown, from the California Institute of Technology was one of the astronomers who announced the discovery in the Astronomical Journal.

He said: "This would be a real ninth planet. There have only been two true planets discovered since ancient times, and this would be a third.

"It's a pretty substantial chunk of our solar system that's still out there to be found, which is pretty exciting."
