Kepler-1209 and Its Super-Earth
Kepler-1209 is a star 1650 light-years away with one known planet. The host star is 3.09 billion years old and has a mass of 1.23 solar masses and a radius of 1.38 solar radii. Its temperature is 6210 K. The star's reported mass and radius estimates are larger than the Sun's, and its reported temperature is hotter than the Sun's.
The planet Kepler-1209 b is classified as a Super-Earth, a size class that reaches 2.5 times Earth's radius. It was discovered by transit in 2016, when it passed in front of its star from our viewpoint and caused a small dip in observed brightness. Kepler-1209 b orbits every 25.4 days. Its radius is 1.51 Earth radii, larger than Earth's.
