IT`S more than 30 times the size of Jupiter and has a temperature of just 350C , but it`s not a planet. The newly discovered object is the coldest observed example of a brown dwarf star, the small and relatively cool stars that make up the majority of matter in the universe. Astronomers are hailing the discovery as a missing link in the evolution of the cosmos which will help to fill the gap between the creation of stars and planets.

Cool: a brown dwarf 65 times the mass of Jupiter, but too small to be a star.
