WASP-37 is a G-type main-sequence star about 1,240 light-years away in the constellation of Virgo.
خصائص النجم
WASP-37 has a low metallicity of just 40% of solar,[4] and is likely older than the Sun.[7] WASP-37 does not have noticeable flare activity.[9]
Planetary system
The hot Jupiter class planet WASP-37b was discovered around WASP-37 in 2010.[4] A study in 2018 found that the stability of orbits in the habitable zone of WASP-37 is not significantly affected by WASP-37b.[10]
