Kepler-689 and Its Neptune-Like Planet
Kepler-689 is a star located 3690 light-years away. It has 0.91 solar masses, 0.88 solar radii, and a temperature of 5520 K, and it is 4.57 billion years old. Its reported mass and radius estimates are smaller than the Sun's, and its reported temperature is cooler than the Sun's.
One planet orbits this star. Kepler-689 b is a Neptune-like planet discovered by transit in 2016. Repeated dips in the star's brightness revealed its orbital period of 22.4 days. Its radius is 2.89 Earth radii, larger than Earth's.
