WASP-88

WASP-88 is a G-type main-sequence star located approximately 474 light-years away in the constellation Pictor. It is the primary component of the WASP-88 system, which also includes a hot Jupiter exoplanet designated WASP-88b.

Stellar Characteristics:

WASP-88 is a relatively Sun-like star, although it is slightly larger and more massive than our Sun. Its spectral type is G8V. The star's effective temperature is around 5500 Kelvin, indicating a surface temperature similar to the Sun. Its metallicity is also relatively similar to the Sun, suggesting a comparable composition of heavier elements.

Planetary System:

The star is known to host one confirmed exoplanet, WASP-88b.

WASP-88b:

WASP-88b is a hot Jupiter, a type of gas giant exoplanet characterized by its large size and proximity to its host star. It has a mass of approximately 0.57 Jupiter masses and a radius of roughly 1.63 Jupiter radii. WASP-88b orbits WASP-88 extremely closely, with an orbital period of about 4.96 days. This close proximity results in very high temperatures for the planet, making it a hot Jupiter. The planet was discovered through the transit method, where the planet passes in front of its star, causing a slight dimming in the star's light. The hot Jupiter's equilibrium temperature is estimated to be over 1,700 K.
