Kepler-750 and Its Two Planets

Kepler-750 is a star 4230 light-years away whose reported mass of 1.15 solar masses is larger than the Sun's. Its radius of 1.23 solar radii is likewise larger than the Sun's, and its temperature of 6160 K is hotter than the Sun's. The star is 3.09 billion years old. Two planets are known to orbit this host, both discovered in 2016 by the transit method, in which a planet passing in front of its star slightly dims the observed brightness.

Kepler-750 b is a Neptune-like planet with a radius of 3.07 Earth radii, larger than Earth's, and it takes 9.43 days to complete one orbit. Kepler-750 c is a Super-Earth with a radius of 1.62 Earth radii, also larger than Earth's, orbiting in 4.09 days.

Among the listed planets, Kepler-750 b has the largest radius, at 3.07 Earth radii, and Kepler-750 c the smallest, at 1.62 Earth radii. In keeping with those sizes, Kepler-750 c has the shortest year by reported estimates, at 4.09 days, while Kepler-750 b has the longest, at 9.43 days.
