11 Oph b
11 Oph b
11 Oph b is an exoplanet orbiting the star 11 Oph, located about 472.9 light-years (145.0 pc) away from Solar System. Its discovery was publicly announced on 2007.
The host star 11 Oph has apparent magnitude of 14.0, with absolute magnitude of 8.2. It is 0.0 times more massive and 0.0 times bigger compared with our Sun. The surface temperature is 2375 with its spectral types of M9
In this planetary system, the extrasolar planet 11 Oph b orbits around the star 11 Oph every 730000.0 days with its orbital distance of 243.00 AU ( 36352282580.1 km)
(Projected orbit of 11 Oph b around its host star 11 Oph)
The Star 11 Oph 's habitable zone is located at the following distance
