[edit] Planetary system
An extrasolar planet, designated TrES-1 was discovered by the Trans-Atlantic Exoplanet Survey by detecting the transit of the planet across its parent star using a small 4-inch diameter telescope. The discovery was confirmed by the Keck Observatory using the radial velocity method, allowing its mass to be determined.
