TOI-7166: A Cool Red Dwarf and Its Super-Earth

TOI-7166 is an M4.5+/-0.5 star located 116 light-years away. This small, cool red dwarf has a reported upper limit of 4 billion years for its age, a mass of 0.19 solar masses, a radius of 0.222 solar radii, and a temperature of 3100 K. Its reported mass estimate is smaller than the Sun's, its reported radius estimate is smaller than the Sun's, and its reported temperature is cooler than the Sun's. One known planet orbits this host.

TOI-7166 b is a Super-Earth discovered by the transit method in 2025. It has an orbital period of 12.9 days and a radius of 2.01 Earth radii, larger than Earth's.
