TOI-1231 b is a Neptune-like exoplanet (an ice giant with a thick atmosphere), about 3.6 times the radius of Earth. With an equilibrium temperature of 330 K (57°C), it lies within the habitable zone where liquid water could potentially exist on its surface. The planet completes one orbit around its star every 24.2 Earth days. It was discovered in 2021 using the transit method. It orbits the M-type star TOI-1231, located approximately 28 parsecs (90 light-years) from Earth.
