GJ 2030 c
GJ 2030 c
GJ 2030 c is an exoplanet orbiting the star GJ 2030, located about 122.4 light-years (37.5 pc) away from Solar System. Its discovery was publicly announced on 2022.
The host star GJ 2030 has apparent magnitude of 6.2, with absolute magnitude of 3.3. It is 1.0 times more massive and 1.0 times bigger compared with our Sun. The surface temperature is 5660 with its spectral types of G5/6V
In this planetary system, the extrasolar planet GJ 2030 c orbits around the star GJ 2030 every 25635.0 days with its orbital distance of 16.75 AU ( 2506063530.0 km)
(Projected orbit of GJ 2030 c around its host star GJ 2030)
