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

[5][2][3] 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.

[5][8] Additional planets in the systems are suspected due to transit timing variations of TrES-1b.
