TOI-1201: A Cool Red Dwarf and Its Super-Earth
TOI-1201 is an M2.0 V star, a small, cool red dwarf, located 124 light-years away. Its reported mass estimate is 0.512 solar masses and its reported radius estimate is 0.508 solar radii, both smaller than the Sun's. The star's reported temperature is 3480 K, cooler than the Sun's. One known planet orbits this host.
That planet is TOI-1201 b, a Super-Earth discovered by transit in 2021. Its reported radius estimate is 2.42 Earth radii, larger than Earth's, and its reported mass estimate is 6.28 Earth masses, also larger than Earth's. It completes an orbit every 2.49 days. Its mean density is 2.46 g/cm³, 0.446 times Earth's.
