GSC 03949-00967 is a G-type main-sequence star about 1179 light-years away in the constellation Cygnus. It is older than the Sun, yet is enriched in heavy elements compared to the Sun, having 160% of the solar abundance. It hosts one known exoplanet, TrES-5b.[4]
The designation GSC 03949-00967 comes from the Guide Star Catalog.
The star is sometimes called TrES-5,[7] in reference to its planet discovered by the Trans-Atlantic Exoplanet Survey (TrES). The discovery paper[4] and the SIMBAD database[6] use this designation for the planet itself, but other sources call the star TrES-5 and the planet TrES-5b,[5][8] following the standard exoplanet naming convention.
In 2011, a transiting hot Jupiter planet, TrES-5b, was detected by the Trans-Atlantic Exoplanet Survey.[4] The host star was one of the faintest stars to host a planetary companion detected by the transit method at the time of discovery.[2] The planet’s equilibrium temperature is 1480±24 K.[5]
An additional planet on a 4-day orbit in the system was suspected since 2018 based on transit-timing variations,[8] but refuted in 2021. A different object on a wide orbit, either star or planet, is still suspected.[9]
