Wolf 359 c
Wolf 359 c
Wolf 359 c is an exoplanet orbiting the star Wolf 359, located about 7.9 light-years ( 2.4 pc) away from Solar System. Its discovery was publicly announced on 2019.
The host star Wolf 359 has apparent magnitude of 13.5, with absolute magnitude of 16.6. It is 1.4 times more massive and 0.2 times bigger compared with our Sun. The surface temperature is 3100 with its spectral types of M6V
In this planetary system, the extrasolar planet Wolf 359 c orbits around the star Wolf 359 every 2.7 days with its orbital distance of 0.02 AU ( 2692761.7 km)
