Kepler-842 b: A Super-Earth Orbiting a Cool, Small Star
Kepler-842 is a star located 1740 light-years away, and it hosts one known planet. The star's reported mass estimate is smaller than the Sun's, at 0.78 solar masses, and its reported radius estimate is also smaller than the Sun's, at 0.73 solar radii. Kepler-842's reported temperature is cooler than the Sun's, at 4850 K, and it is 4.37 billion years old.
The planet Kepler-842 b is a Super-Earth, a size class that reaches 2.5 times Earth's radius, and its reported radius estimate is larger than Earth's at 1.6 Earth radii. It was discovered by the transit method in 2016. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness, and repeated dips help establish orbital periods. Kepler-842 b completes one orbit in 1.22 days, the length of its year.
