LHS 1815 b: A Nearby Earth-Like World
LHS 1815 is a small, cool red dwarf of spectral type M1, located 97.3 light-years away. The star has a reported mass of 0.502 solar masses, a reported radius of 0.501 solar radii, and a temperature of 3640 K. Its mass, radius, and temperature are all smaller or cooler than the Sun's. One planet orbits this host.
That planet is LHS 1815 b, an Earth-like world discovered by transit in 2020. It has a mass of 1.58 Earth masses, a radius of 1.09 Earth radii, and an orbital period of 3.81 days. Its radius is larger than Earth's, and its mean density is 6.76 g/cm³, 1.23 times Earth's.
