Kepler-266 and Its Two Known Planets
Kepler-266 is a star 4470 light-years away, and it hosts two known planets. The star is 4.79 billion years old, with a mass of 0.91 solar masses and a radius of 0.88 solar radii. Its temperature is 5520 K, cooler than the Sun's.
Both planets were discovered by transit in 2014, the method in which a planet passes in front of its star from our viewpoint and causes a small dip in observed brightness. Kepler-266 b is classified as a Super-Earth and orbits every 6.62 days. Its radius is 2.48 Earth radii, larger than Earth's and the smallest among the listed planets. Kepler-266 c is Neptune-like, with an orbital period of 108 days. Its radius is 3.89 Earth radii, larger than Earth's and the largest among the listed planets. Among these planets, Kepler-266 b has the shortest year and Kepler-266 c the longest.
