Star characteristics
WASP-37 has a low metallicity of just 40% of solar,[5] and is likely older than Sun.[2] WASP-37 does not have noticeable flare activity.[6]
Planetary system
The "Hot Jupiter" class planet WASP-37b was discovered around WASP-37 in 2010.[5] The study in 2018 has found the stability of orbits in habitable zone of WASP-37 is not significantly affected by WASP-37b planet.[7]
