GSC 03949-00967
GSC 03949-00967 is a G-type main-sequence star about 1179 light-years away. It is older than the Sun, yet is enriched by heavy elements compared to the Sun, having 160% of solar abundance.
Planetary system
TrES-5b
In 2011 a transiting hot Jupiter planet TrES-5b was detected. The host star was one of the faintest stars to which a planetary companion was detected by the transit method at the time of discovery. The planet’s equilibrium temperature is 1480±24 K.
TrES-5c/TrES-5B
An additional planet on a 4-day orbit in the system was suspected since 2018, but refuted in 2021. Another object on a wide orbit, either star or planet, is still suspected.
