Planetary system In 2011 a transiting hot Jupiter planet TrES-5 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 . 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.
