Kepler-1447 and Its Neptune-Like Planet
Kepler-1447 is a star located 2900 light-years away. It has 0.97 solar masses, 0.95 solar radii, and a temperature of 5720 K, and it is 4.17 billion years old. One planet orbits this host.
That planet is Kepler-1447 b, a Neptune-like world discovered in 2016 by the transit method, in which a planet passes in front of its star from our viewpoint and causes a small dip in observed brightness. Repeated dips help establish orbital periods, and Kepler-1447 b completes one orbit every 56.7 days. Its radius is 2.9 Earth radii, a size estimate larger than Earth's.
