TrES-3 has twice Jupiter’s mass and 1.3 its radius. Moreover, it’s evidently unstable, as per Greg Laughlin, who described it on systemic as “…undergoing orbital decay as a result of tidal evolution, and sooner or later it’s going to merge with its parent star.” Transits are almost daily, leading Laughlin to call TrES-3 “…a great starter world for Northern Hemisphere observers who want to bag their first extrasolar planet.” The planet’s home star, GSC 03089-00929, is somewhat smaller than the Sun and some 1500 light years away.
