WASP 10b

WASP-10b is an extrasolar planet discovered in 2008 by SuperWASP using the transit method. Follow-up radial velocity observations showed that it is three times more massive than Jupiter, while the transit observations showed that its radius is 8% bigger than Jupiter, quite small for a Hot Jupiter but this is due to its high mass. This makes the density of this planet similar to our Moon. Its takes 3 days to orbit around the star, in contrast to 365 days for the Earth to go around the Sun. It is the only confirmed extrasolar planet in WASP-10's planetary system, since the only other detected planet in WASP-10's planetary system, WASP-10c, is still unconfirmed.
