TrES-4 b
TrES-4 b
TrES-4 b is an exoplanet orbiting the star TrES-4, located about 1562.3 light-years (479.0 pc) away from Solar System. Its discovery was publicly announced on 2007.
The host star TrES-4 has apparent magnitude of 11.6, with absolute magnitude of 3.2. It is 1.4 times more massive and 1.8 times bigger compared with our Sun. The surface temperature is 6200 with its spectral types of F
In this planetary system, the extrasolar planet TrES-4 b orbits around the star TrES-4 every 3.6 days with its orbital distance of 0.05 AU ( 7605555.7 km)
