TOI-5489: A Cool Star With Two Small Planets
TOI-5489 is a star 147 light-years away with two known planets. The star has a mass of 0.409 solar masses and a radius of 0.416 solar radii, both smaller than the Sun's, and a temperature of 3550 K, cooler than the Sun's.
Both planets were discovered by transit in 2025 and are classified as Earth-like, meaning their radii stay within 1.5 times Earth's radius. TOI-5489 b has a radius of 1.4 Earth radii and completes an orbit every 3.15 days. TOI-5489 c has a radius of 1.28 Earth radii and orbits every 4.92 days. Among the listed planets, TOI-5489 b has the shortest year and the largest radius, while TOI-5489 c has the longest year and the smallest radius. Both planets are larger than Earth.
