WASP-95 is a star 451 light-years (138 parsecs ) away in the constellation Grus. With an apparent magnitude of 10.1, it is not visible to the naked eye. Its spectral type of G2 means it is a yellow sunlike star.

Planetary system

In 2013, a planet was discovered around WASP-95. The planet, WASP-95b, is a hot Jupiter about 10% more massive than Jupiter, and completes an orbit round its star every two days. It was discovered by its transit of the star in 2013. [5] The planet's equilibrium temperature is 1692.6±40.4 K. [6]
