Kepler-1709 and Its Neptune-Like Planet
Kepler-1709 is a star 893 light-years away with one known planet. The star has a mass of 1.04 solar masses, a radius of 1.14 solar radii, and a temperature of 5790 K. Its reported radius estimate is larger than the Sun's.
The planet Kepler-1709 b is Neptune-like, discovered in 2021 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-1709 b's orbital period is 65.7 days. Its radius is 3.12 Earth radii, larger than Earth's. A Neptune-like planet reaches 4 times Earth's radius.
