TOI-2081: A Cool Red Dwarf and Its Super-Earth
TOI-2081 is an M1.0 star located 203 light-years away. Its spectral type places it among the cooler, redder stars. The star has a mass of 0.54 solar masses, a radius of 0.534 solar radii, and a temperature of 3800 K. Each of these values is smaller or cooler than the Sun's corresponding value. One planet is known to orbit this host.
That planet is TOI-2081 b, a Super-Earth discovered by transit in 2022. It orbits every 10.5 days, and its radius is 2.04 Earth radii, larger than Earth's.
