Kepler-1442 b: A Neptune-Like World in a Distant System
Kepler-1442 is a star located 1990 light-years away, and it hosts one known planet. The star is estimated to be 1.7 billion years old and has a mass of 1.34 solar masses, a radius of 1.44 solar radii, and a temperature of 6390 K. Its reported mass and radius estimates are larger than the Sun's, and its reported temperature is hotter than the Sun's.
The sole planet in this system is Kepler-1442 b, a Neptune-like world discovered by the transit method in 2016. It orbits its star with an orbital period of 81.4 days and has a radius of 3.93 Earth radii, which is larger than Earth's radius. This radius places it within the Neptune-like size class, which extends to 4 times Earth's radius.
