TOI-871: A Cool Dwarf with a Super-Earth
TOI-871 is a star 222 light-years away with one known planet in orbit. It is 5.9 billion years old and has a mass of 0.758 solar masses, a radius of 0.719 solar radii, and a temperature of 4930 K. Its mass and radius are smaller than the Sun's, and its temperature is cooler than the Sun's.
The planet, TOI-871 b, is a Super-Earth discovered by transit in 2024. It orbits every 14.4 days. Its radius is 1.66 Earth radii, larger than Earth's. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness; repeated dips help establish orbital periods.
