Planetary system
In 2011 a transiting hot Jupiter planet TrES-5 was detected.[4] The host star was one of the faintest stars to which a planetary companion was detected by transit method at time of discovery.[2] The planet equilibrium temperature is 1480±24 K.[5]
An additional planet in system is suspected since 2018.[6]
