The head of celebrity physicists Brian Cox has been officially designated as a new planet.
The announcement was made after a meeting of the International Federation of Space Scientists in Geneva.
Previously Prof Cox's giant noggin was classed as an asteroid.
A spokescientist for the federation, Dr Hannah Brainacre, said Prof Cox's head had finally reached planet-sized proportions thanks to recent media exposure.
Dr Brainacre said: "In particular, the Christmas lecture at the Royal Institute where Prof Cox cavorted with stars of film and television led to a significant head expansion.
"He skipped rope with Simon Pegg and did sums with Jonathan Ross - it was a real hoot, did you see it?"
During the lecture, Prof Cox showed-off just how smart and better than everyone he really is.
A public competition run to name the new celestial body has been won by eight-year-old Lucy Swanson from Stains with her entry 'Unicorn Susan 7'.
The scientific community is now debating whether or not Unicorn Susan 7 could host intelligent life.
While some say there is a possibility, others claim there is far too much hot air.
