SOI-2 b
SOI-2 b
SOI-2 b is an exoplanet orbiting the star SOI-2. Its discovery was publicly announced on 2023.
The host star SOI-2 has apparent magnitude of 22.0, with absolute magnitude of 25.0. It is 0.7 times more massive and 0.6 times bigger compared with our Sun. The surface temperature is 3300 with its spectral types of M9
In this planetary system, the extrasolar planet SOI-2 b orbits around the star SOI-2 every 2.1 days with its orbital distance of 0.03 AU ( 4262955.6 km)
(Projected orbit of SOI-2 b around its host star SOI-2)
The Star SOI-2 's habitable zone is located at the following distance
