7 CMA c
7 CMA c
7 CMA c is an exoplanet orbiting the star 7 CMa, located about 354.0 light-years (108.5 pc) away from Solar System. Its discovery was publicly announced on 2019.
The host star 7 CMa has apparent magnitude of 4.0, with absolute magnitude of -1.2. It is 1.5 times more massive and 2.3 times bigger compared with our Sun. The surface temperature is 4792 with its spectral types of K1 III
In this planetary system, the extrasolar planet 7 CMA c orbits around the star 7 CMa every 988.9 days with its orbital distance of 2.14 AU ( 320588236.9 km)
