iot Cap c
iot Cap c
iot Cap c is an exoplanet orbiting the star iot Cap, located about 201.4 light-years (61.7 pc) away from Solar System. Its discovery was publicly announced on 2022.
The host star iot Cap has apparent magnitude of 4.3, with absolute magnitude of 0.3. It is 2.9 times more massive and 10.7 times bigger compared with our Sun. The surface temperature is 5200 with its spectral types of G7III
In this planetary system, the extrasolar planet iot Cap c orbits around the star iot Cap every 2481.1 days with its orbital distance of 5.07 AU ( 758012410.8 km)
