WASP-95 is a star 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.[4] The planet equilibrium temperature is 1692.6±40.4 K.[5]
