K2-417 is an M V star, a small, cool red dwarf, located 307 light-years away. Its reported mass estimate is 0.569 solar masses, and its reported radius estimate is 0.578 solar radii, both smaller than the Sun's corresponding values. The star's reported temperature is 3860 K, cooler than the Sun's. One planet orbits this host.
That planet is K2-417 b, a Neptune-like world discovered by the transit method in 2023. With a radius of 3.31 Earth radii, it is larger than Earth. Its reported mass carries an upper limit of 699.2224954 Earth masses, and it completes one orbit every 6.54 days.
