WASP-107b is a super-Neptune exoplanet that orbits the star WASP-107. It lies 200 light-years away from Earth in the constellation Virgo. Its discovery was announced in 2017 and led by D. R. Anderson and a team of colleagues via the WASP-South.
WASP-107b is a super-Neptune gas-giant exoplanet located 200 light years away from Earth in the constellation Virgo. It is roughly the size of Jupiter but only one-eighth of Jupiter’s mass, making it one of the lowest density exoplanets. Its radius is 0.94 times Jupiter's, making its atmosphere fluffy, and coupled with transiting a moderately bright K star makes it a target for atmosphere characterization. It is eight times nearer its star than Mercury is to the Sun and orbits its star every 5.7 days. With a temperature of 932 °F (500 °C), its atmosphere makes it one of the hottest known exoplanets.
