TOI-203 b
TOI-203 b
TOI-203 b is an exoplanet orbiting the star TOI-203, located about 80.9 light-years (24.8 pc) away from Solar System. Its discovery was publicly announced on 2018.
The host star TOI-203 has apparent magnitude of 15.0, with absolute magnitude of 13.0.
In this planetary system, the extrasolar planet TOI-203 b orbits around the star TOI-203 every 52.0 days with its orbital distance of 0.00 AU ( 0.0 km)
(Projected orbit of TOI-203 b around its host star TOI-203)
The Star TOI-203 's habitable zone is located at the following distance
