GSC 02652-01324 is an orange dwarf main sequence star approximately 521 light-years away in the constellation of Lyra (the Lyre).

Planetary system

In 2004 the extrasolar planet TrES-1b was found to be orbiting this star by the Trans-Atlantic Exoplanet Survey using the transit method. The planet was detected crossing its parent star using a small 4-inch-diameter (100 mm) telescope. The discovery was confirmed by the Keck Observatory using the radial velocity method, allowing its mass to be determined.

Additional planets in the systems are suspected due to transit timing variations of TrES-1b.
