WASP-8 is a magnitude 9.9 main-sequence yellow dwarf star. It is reported to be a G-type star of temperature 5600 K, mass of 0.93 solar masses, radius of 0.93 solar radius, and a luminosity of 0.79 of solar luminosity.

Planetary system

The star is orbited by two known extrasolar planet, designated WASP-8b and WASP-8c. They was catalogued as part of the SuperWASP mission and discovered by the astronomical transit method. WASP-8c has the longest orbital period of any exoplanet discovered by WASP with a period of 4,323 days, over 400 times the period of the second-furthest planet, WASP-117b with a period of 10.02 days.

Measurements of WASP-8b's radius and mass give it an estimated density of 2.53 g/cm3, about twice the density of Jupiter.
