TrES-2 A b
TrES-2 A b
TrES-2 A b is an exoplanet orbiting the star TrES-2 A, located about 717.5 light-years (220.0 pc) away from Solar System. Its discovery was publicly announced on 2006.
The host star TrES-2 A has apparent magnitude of 11.4, with absolute magnitude of 4.7. It is 1.0 times more massive and 1.0 times bigger compared with our Sun. The surface temperature is 5850 with its spectral types of G0V
In this planetary system, the extrasolar planet TrES-2 A b orbits around the star TrES-2 A every 2.5 days with its orbital distance of 0.04 AU ( 5318204.3 km)
