WASP-48b is an extrasolar planet orbiting the star WASP-48 in the constellation Cygnus. The planet was detected using the transit method by the SuperWASP team, which published its discovery in 2011. It orbits its host star in just 2.14 days with a semi-major axis of 0.034 AU[3] and has an equilibrium temperature of 1956±54 K.[4] The dayside temperature was measured to be around 2300 K in 2018.[2]
