Gaia-1 b
Gaia-1 b
Gaia-1 b is an exoplanet orbiting the star Gaia-1, located about 1201.2 light-years (368.3 pc) away from Solar System. Its discovery was publicly announced on 2021.
The host star Gaia-1 has apparent magnitude of 13.2, with absolute magnitude of 5.4. It is 0.9 times more massive and 1.0 times bigger compared with our Sun. The surface temperature is 5370 with its spectral types of G7
In this planetary system, the extrasolar planet Gaia-1 b orbits around the star Gaia-1 every 3.0 days with its orbital distance of 0.04 AU ( 6054225.8 km)
(Projected orbit of Gaia-1 b around its host star Gaia-1)
The Star Gaia-1 's habitable zone is located at the following distance
