TOI-1801 b: A Super-Earth Orbiting an M-Type Dwarf

TOI-1801 is an M0.5+/-0.5 V star, an M-type dwarf, located 100 light-years from Earth. Its reported mass is 0.556 solar masses, its radius is 0.547 solar radii, and its temperature is 3860 K; these values are smaller or cooler than the Sun's corresponding values. Its age is 0.7 billion years.

One planet orbits this host: TOI-1801 b, a Super-Earth discovered in 2023 by the transit method. It has a radius of 2.08 Earth radii, larger than Earth's, and a mass of 5.74 Earth masses, also larger than Earth's. Its mean density is 3.52 g/cm³, 0.639 times Earth's. The planet completes an orbit every 10.6 days.
