Kepler-728 and Its Neptune-Like Planet
Kepler-728 is a star located 5760 light-years away. It has one known planet. The host star is 4.07 billion years old and has a mass of 0.95 solar masses and a radius of 0.93 solar radii, with a temperature of 5660 K.
The planet Kepler-728 b is Neptune-like, a size class that reaches four times Earth's radius. It was 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. Kepler-728 b orbits its star every 5.74 days and has a radius of 3.34 Earth radii, a reported estimate larger than Earth's.
