Star in the constellation Equuleus
WASP-90 is a faint 11th magnitude star located in the northern constellation Equuleus . With an apparent magnitude of 11.63, it is too faint to be detected with the naked eye, but can be seen with a telescope, and is located 1,560 ly (480 pc ) from the Solar System .
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 6,430 K . Despite it being a similar age to the Sun, the star has a high metallicity that is 28% greater than that of the Sun.[ 4]
Planetary system
In 2016, a bloated "hot Jupiter" was discovered orbiting the star. Due to the host's state, the planet is extremely irradiated.
