WASP-16 is amagnitude 11yellow dwarfmain sequencestar, with characteristics similar to theSun,[5] located in theVirgoconstellation.[1]
In 2009, a planet of the star was announced by theSuperWASP project. It appears to be anotherhot Jupiter type exoplanet.[4]
In 2024, a candidatemini-neptune was detected, also using thetransit method. Further observations are needed to confirm its existence. The planet takes ten days to fully orbit WASP-16 and has anequilibrium temperature of 810 K (537 °C).[7]
