HD 260655 and Its Two Planets
HD 260655 is an M0 V star, a small, cool red dwarf, located 32.6 light-years away. Its reported mass and radius are each 0.439 solar masses and 0.439 solar radii, both smaller than the Sun's, and its temperature of 3800 K is cooler than the Sun's. The star is 5 billion years old, and two planets are known to orbit it.
Both planets were discovered by transit in 2022. HD 260655 b is classified as Earth-like, with a radius of 1.24 Earth radii and a mass of 2.14 Earth masses, both larger than Earth's. It completes an orbit in 2.77 days. Its mean density is 6.18 g/cm³, 1.12 times Earth's. Among the listed planets, HD 260655 b has the shortest year, the smallest radius, and the smallest reported mass.
HD 260655 c is classified as a Super-Earth. Its radius is 1.53 Earth radii and its mass is 3.09 Earth masses, each larger than Earth's. It orbits in 5.71 days, and its mean density is 4.73 g/cm³, 0.858 times Earth's. Among the listed planets, HD 260655 c has the longest year, the largest radius, and the largest reported mass.
