WASP-43 is a K-type star in the Sextans constellation. It is about half the size of the Sun and has approximately half the mass. WASP-43 has one known planet in orbit a Hot Jupiter called WASP-43b. At the time of publishing of WASP-43b’s discovery on April 15 2011 the planet was the most closely orbiting Hot Jupiter discovered. The small orbit of WASP-43b is thought to be caused by WASP-43’s unusually low mass.
