Planetary system

In 2009, a planet of the star was announced by the SuperWASP project. It is another hot Jupiter type exoplanet. [4]

In 2024, a candidate mini-neptune was detected, also using the transit method. Further observations are needed to confirm its existence. The planet takes ten days to fully orbit WASP-16 and has an equilibrium temperature of 810  K (537 °C). [7]
