Roque 12 b
Roque 12 b
Roque 12 b is an exoplanet orbiting the star Roque 12, located about 379.3 light-years (116.3 pc) away from Solar System. Its discovery was publicly announced on 2002.
The host star Roque 12 has apparent magnitude of 22.0, with absolute magnitude of 16.7. It is 0.1 times more massive and 0.1 times bigger compared with our Sun. The surface temperature is 2900 with its spectral types of M7.5
In this planetary system, the extrasolar planet Roque 12 b orbits around the star Roque 12 every 70.0 days with its orbital distance of 0.13 AU ( 19467687.8 km)
(Projected orbit of Roque 12 b around its host star Roque 12)
The Star Roque 12 's habitable zone is located at the following distance
Inner Boundary (the orbital distance at Venus's Equivalent Radiation )
: 0.024 AU ( 3543214.6 km)
Earth Boundary (the orbital distance at Earth's Equivalent Radiation)
: 0.033 AU ( 4897648.6 km)
Outer Boundary (the orbital distance at Mars's Equivalent Radiation)
: 0.050 AU ( 7462932.6 km)
