LHS 3154 and Its Close-Orbiting Planet

LHS 3154 is a star 51.4 light-years away with a spectral type of M6.5, placing it among the small, cool red dwarfs. It has an age of 5 billion years, a mass of 0.112 solar masses, a radius of 0.141 solar radii, and a temperature of 2860 K. Its reported mass and radius are smaller than the Sun's, and its temperature is cooler than the Sun's. One planet is known to orbit this host.

That planet, LHS 3154 b, was discovered in 2023 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. It has a minimum mass of 13.2 Earth masses, larger than Earth's, and an orbital period of 3.72 days.
