data

GSC 02652-01324 is an orange dwarf main sequence star approximately 512 light-years away in the constellation of Lyra (the Lyre).[1]

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.[2]
