Kepler-290: A Cool Star With Three Small Worlds
Kepler-290 is a star located 2270 light-years away. It is 4.47 billion years old and has a mass of 0.79 solar masses, a radius of 0.75 solar radii, and a temperature of 4960 K. Its mass and radius are smaller than the Sun's, and its temperature is cooler than the Sun's. Three planets orbit this host.
Kepler-290 b is a Super-Earth discovered by transit in 2014. It completes one orbit every 14.6 days and has a radius of 2.25 Earth radii, larger than Earth's. Kepler-290 c is a Neptune-like planet, also found by transit in 2014. Its orbital period is 36.8 days and its radius is 2.7 Earth radii, larger than Earth's. Kepler-290 d is a Sub-Earth discovered by transit in 2023. It orbits in just 0.764 days with a radius of 0.86 Earth radii, smaller than Earth's.
Among the listed planets, Kepler-290 d has the shortest year and smallest radius, while Kepler-290 c has the longest year and largest radius. Kepler-290 b has the second-shortest year and second-smallest radius.
