WASP-13 b
Description: WASP-13b, also known as Cruinlagh, is an extrasolar planet that was discovered in 2008 in the orbit of the sunlike star WASP-13. The planet has a mass of nearly half that of Jupiter, but a radius five-quarters of the size of Jupiter. This low relative mass might be caused by a core that is of low mass or that is not present at all.
