GQ Lupi is a T Tauri variable star approximately 495 light-years away in the constellation of Lupus. The star is young and has about 70% of the Sun's mass.
Possible planetary system.
In 2005, Ralph Neuhäuser and his colleagues reported a substellar object, GQ Lupi b, orbiting the star. Along with 2M1207b, this was one of the first extrasolar planet candidates to be directly imaged. The image was made with the VLT telescope at Paranal Observatory, Chile, on June 25
TrES-4b
TrES-4b is an extrasolar planet, and one of the largest exoplanets ever found, after WASP-12b, WASP-17b, CT Chamaeleontis b (though the latter may be a brown dwarf) and GQ Lupi b. It was discovered in 2006, and announced in 2007, by the Trans-Atlantic Exoplanet Survey, using the transit method. It is approximately away orbiting the star GSC 02620-00648, in the constellation Hercules.
TrES-4 orbits its primary star every 3.543 days and eclipses it when viewed from Earth. The planet is
