tau Boo A b
tau Boo A b
tau Boo A b is an exoplanet orbiting the star tau Boö A, located about 50.9 light-years (15.6 pc) away from Solar System. Its discovery was publicly announced on 1996.
The host star tau Boö A has apparent magnitude of 4.5, with absolute magnitude of 3.5. It is 1.3 times more massive and 1.3 times bigger compared with our Sun. The surface temperature is 6309 with its spectral types of F7 V
In this planetary system, the extrasolar planet tau Boo A b orbits around the star tau Boö A every 3.3 days with its orbital distance of 0.05 AU ( 6881502.1 km)
