TOI-277: A Cool Red Dwarf and Its Close-Orbiting Planet

TOI-277 is a star 211 light-years away with a reported mass of 0.16 solar masses, a radius of 0.362 solar radii, and a temperature of 4030 K. Its reported mass and radius estimates are smaller than the Sun's, and its reported temperature is cooler than the Sun's. One planet is known to orbit this host.

That planet, TOI-277 b, is Neptune-like and was discovered by transit in 2022. It has an orbital period of 3.99 days and a radius of 2.65 Earth radii. Its reported radius estimate is larger than Earth's.
