RR Cae b
RR Cae b
RR Cae b is an exoplanet orbiting the star RR Cae. Its discovery was publicly announced on 2012.
The host star RR Cae has apparent magnitude of 14.4, with absolute magnitude of 25.0. It is 0.6 times more massive and 0.6 times bigger compared with our Sun. The surface temperature is 5500 with its spectral types of DAZ8+dM
In this planetary system, the extrasolar planet RR Cae b orbits around the star RR Cae every 4350.0 days with its orbital distance of 5.30 AU ( 792868714.7 km)
(Projected orbit of RR Cae b around its host star RR Cae)
The Star RR Cae 's habitable zone is located at the following distance
Inner Boundary (the orbital distance at Venus's Equivalent Radiation )
: 0.364 AU ( 54489240.5 km)
Earth Boundary (the orbital distance at Earth's Equivalent Radiation)
: 0.503 AU ( 75318370.1 km)
Outer Boundary (the orbital distance at Mars's Equivalent Radiation)
: 0.767 AU ( 114768528.2 km)
