Properties

WASP-90 has a classification of F6. The exoplanet discovery paper describes it as having expanded to a "post-MS" radius, about twice that of the Sun. WASP-90 is 55% more massive than the Sun, and radiates at 4.3 times the Sun's luminosity from its photosphere at an effective temperature of. Despite it being a similar age to the Sun, the star has a high metallicity that is 28% greater than that of the Sun.

Planetary system

In 2016, a bloated "hot Jupiter" was discovered orbiting the star. Due to the host's state, the planet is extremely irradiated.
