The Planets

The SuperWASP project is pleased to announce the discovery of 9 new planets. WASP-8b, WASP-21b, WASP-22b, WASP-24b, WASP-25b, WASP-26b, WASP-28b, WASP-29b and WASP-33b were announced on 13th April 2010, and take our planet haul up to Twenty-Six. This page contains information on where you can find our planets, what they're like, and a bit about their parent star. If you'd like to find out more about exoplanets in general, then click here.

Please note that this page is updated periodically from the most recent analyses carried out within the WASP consortium, as we acquire new photometric and radial-velocity data. Please expect planetary and stellar masses and radii, and the ephemerides for times of transit, to improve without notice. As a result, what you see here may not necessarily agree with the values originally published in the discovery papers. We do our best to ensure that the values presented here are the most reliable that can be derived from the data currently available to us.
