A 10th planet - larger than Pluto - has been discovered in the system. The temporary name is 2003UB313, other sources claim it will be called Sedna, like the Inuit Goddess of the Sea.
So can we now expect a frenzy of dogs being christened Sedna? A Sedna chocolate bar? Or a very devilish radio- active substance called Sednaium? Or should they simply come up with a better name? Answers on a postcard please!
