TOI-2285 b is a sub-Neptune exoplanet in orbit around the M-type star TOI-2285.[3][4]
The planet was identified through transit signals in data from the Transiting Exoplanet Survey Satellite (TESS).[1]
Initially, researchers reported an orbital period of 27.3 days, which put the planet near the outer edge of the habitable zone with an equilibrium temperature around 284 K (11 °C). Later analysis of additional TESS sectors revealed that the true period is 13.64 days. This correction increases the estimated equilibrium temperature to 358 K (85 °C).[2]
