TrES-4b is an exoplanet, one of the largest exoplanets ever found. It was discovered in 2006, and announced in 2007, by the Trans-Atlantic Exoplanet Survey, using the transit method. It is approximately 1,400 light-years (430 pc) away orbiting the star GSC 02620-00648, in the constellation Hercules. [1]

Oct 24, 2024 · TrES-4 b is a gas giant exoplanet that orbits a F-type star. Its mass is 0.78 Jupiters, it takes 3.6 days to complete one orbit of its star, and is 0.05084 AU from its star. Its discovery was announced in 2007.

Aug 8, 2007 · This computer-generated image of planet TrES-4 depicts its host star (right), bigger and hotter than the Sun and about 10 times larger than the planet.

Aug 6, 2007 · Dubbed TrES-4, the planet is about 1.7 times the size of Jupiter and belongs to a small subclass of "puffy" planets that have extremely low densities. The finding will be detailed...

Aug 6, 2007 · It has been named TrES-4, to indicate that it is the fourth planet detected by the Trans-atlantic Exoplanet Survey (TrES) network of telescopes. An international team of astronomers has discovered the largest-radius and lowest-density exoplanet of all those whose mass and radius are known.

A computer-generated simulation of TrES-4, with its host star on the right. The planet's home star is bigger and hotter than the Sun, and is about ten times larger than the planet. Astronomers speculate that the large size and low density of TrES-4 may cause a small fraction of its outer atmosphere to escape from the planet’s gravitational ...

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 …

Aug 6, 2007 · We report the discovery of TrES-4, a hot Jupiter that transits the star GSC 02620-00648 every 3.55 days. From high-resolution spectroscopy of the star we estimate a stellar effective temperature...
