The star system is much younger than the Sun at 300 million to 1.2 billion years age, and is heavily enriched in heavy elements, having nearly twice the concentration of iron compared to the Sun.

It is reported to be a G-type star with a temperature of 5600 K and has a mass 1.093±0.024, a radius 0.976±0.020 and a luminosity of 0.79 times that of the Sun.

There is a companion star WASP-8B located 4.5 arcseconds away with the same proper motion, indicating a stellar binary system.

[4] The axis orientation of the primary star is uncertain, but it is close to pointing one of the poles to the Earth.

WASP-8b was discovered in 2010 by the astronomical transit method and was catalogued as part of the SuperWASP mission.
