K2-169 b: A Transiting Earth-Like World
K2-169 is a single star located 769 light-years away, with a mass of 0.986 solar masses and a radius of 0.919 solar radii. Its temperature is 5550 K, cooler than the Sun's, and its reported radius estimate is smaller than the Sun's. One planet is known to orbit this host.
That planet, K2-169 b, was discovered by transit in 2018. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. Repeated dips help establish orbital periods.
K2-169 b is classified as Earth-like, a size class that stays within 1.5 times Earth's radius. Its reported radius estimate is 1.27 Earth radii, larger than Earth's. It completes an orbit every 6.38 days.
