WASP-10b is an extrasolar planet discovered in 2008 by SuperWASP using the transit method. It takes about 3 days to orbit around WASP-10. Follow-up radial velocity observations showed that it is three times more massive than Jupiter, while the transit observations showed that its radius is only 8% larger than Jupiter's, giving the planet a density more similar to the Moon than a normal gas giant.[1][2] It is currently the only confirmed planet around WASP-10, as WASP-10c is still unconfirmed.[3]
