Oph 11 b
Oph 11 b
Oph 11 b is an exoplanet orbiting the star Oph 11, located about 472.9 light-years (145.0 pc) away from Solar System. Its discovery was publicly announced on 2007.
The host star Oph 11 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 Oph 11 b orbits around the star Oph 11 every 730000.0 days with its orbital distance of 243.00 AU ( 36352282580.1 km)
(Projected orbit of Oph 11 b around its host star Oph 11)
The Star Oph 11 's habitable zone is located at the following distance
