Kepler-1387 and Its Sub-Earth Planet
Kepler-1387 is a star located 1490 light-years away, and it hosts one known planet. The star is estimated to be 4.37 billion years old, with a mass of 0.82 solar masses and a radius of 0.77 solar radii. Its reported temperature is 5050 K. Compared with the Sun, the star's reported mass estimate is smaller, its reported radius estimate is smaller, and its reported temperature is cooler.
The planet is Kepler-1387 b, a Sub-Earth discovered by transit in 2016. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. Kepler-1387 b completes an orbit every 2.28 days and has a radius of 0.93 Earth radii. Its reported radius estimate is smaller than Earth's.
