Wolf 503 b
Wolf 503 b
Wolf 503 b is an exoplanet orbiting the star Wolf 503, located about 145.4 light-years (44.6 pc) away from Solar System. Its discovery was publicly announced on 2018.
The host star Wolf 503 has apparent magnitude of 10.3, with absolute magnitude of 7.0. It is 0.7 times more massive and 0.7 times bigger compared with our Sun. The surface temperature is 4716 with its spectral types of K3.5V
In this planetary system, the extrasolar planet Wolf 503 b orbits around the star Wolf 503 every 6.0 days with its orbital distance of 0.06 AU ( 8536054.5 km)
