WASP-28b is an extrasolar planet orbiting WASP-28, a magnitude V = 12 star also known as 1SWASP J233427.87-013448.1 and 2MASS 23342787-0134482.[1] Since it orbits its star at a very low distance, the planet is very strongly irradiated.[1] As seen from the Earth, WASP-28b transits its host star every 3.408 days (3.408821 ± 0.000015[1] exactly) during about 3 hours (0.1267 ± 0.0013 days[1]).

Internal structure Edit

The planet seems to be a gas giant with a low core mass (<~10M(Earth)) and a low heavy elements content (Z<~0.2).[1]
