K2-416 is an M V star, a small, cool red dwarf, located 392 light-years away. Its reported mass estimate is 0.548 solar masses and its reported radius estimate is 0.554 solar radii, both smaller than the Sun's. The star's reported temperature is 3750 K, cooler than the Sun's. One planet orbits this host.
That planet is K2-416 b, a Neptune-like world discovered in 2023 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. Its reported radius estimate is 2.66 Earth radii, larger than Earth's. Its mass is reported with an upper limit of 1652.7077164 Earth masses. K2-416 b completes one orbit in 13.1 days.
