A star 600 light years from Earth is slowly devouring one of its own planets, according to a study released on Wednesday. The planet, the discovery of which was reported last year, is a "gas giant" with a mass about 40 per cent greater than that of Jupiter, the biggest planet of our Solar System, and with a radius 79 per cent bigger. But whereas Jupiter takes nearly 12 years to plod around the Sun, it takes WASP-12b a mere 26 hours to race around its star, WASP-12, located in the constellation of Auriga.
