Neptune
Neptune is an exoplanet orbiting the star Sun.
The host star Sun has apparent magnitude of 12.0, 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 5778 with its spectol type of G2V
In this planetary system, the extrasolar planet Neptune orbits around the star Sun every 60189.0 days with its orbital distance of 30.07 AU ( 4498252913.8 km)
(Projected orbit of Neptune around its host star Sun)
The Star Sun 's habitable zone is located at the following distance
Inner Boundary (the orbital distance at Venus's Equivalent Radiation )
: 0.723 AU ( 108196493.8 km)
Earth Boundary (the orbital distance at Earth's Equivalent Radiation)
: 1.000 AU ( 149555829.6 km)
Outer Boundary (the orbital distance at Mars's Equivalent Radiation)
: 1.523 AU ( 227889987.7 km)
Snow Line (the orbital distance at Snow Line Equivalent Radiation)
: 2.242 AU ( 335350100.1 km)
Radiation at Planetary Boundary of Neptune : 1.51 W/m2
(Habitable zone calculated based on SEAU(Solar Equivalent Astronomical Unit) around the star Neptune)
