nu Oph b
nu Oph b
nu Oph b is an exoplanet orbiting the star nu Oph, located about 150.7 light-years (46.2 pc) away from Solar System. Its discovery was publicly announced on 2004.
The host star nu Oph has apparent magnitude of 3.3, with absolute magnitude of 0.0. It is 3.0 times more massive and 15.1 times bigger compared with our Sun. The surface temperature is 4928 with its spectral types of K0III
In this planetary system, the extrasolar planet nu Oph b orbits around the star nu Oph every 530.2 days with its orbital distance of 1.79 AU ( 267780188.6 km)
(Projected orbit of nu Oph b around its host star nu Oph)
The Star nu Oph 's habitable zone is located at the following distance
