Sol i (Neptune)
Sol i (Neptune)
Sol i (Neptune) is an exoplanet orbiting the star Sun. Its discovery was publicly announced on 1846.
The host star Sun has apparent magnitude of 22.0, with absolute magnitude of 25.0. It is 1.0 times more massive and 1.0 times bigger compared with our Sun. The surface temperature is 5670 with its spectral types of G2V
In this planetary system, the extrasolar planet Sol i (Neptune) orbits around the star Sun every 60189.0 days with its orbital distance of 30.07 AU ( 4498252913.8 km)
