K2-110 b: A Neptune-like Planet Orbiting a Cool Dwarf
K2-110 is a K3 V star located 380 light-years away. This K-type main-sequence dwarf has an age of 8 billion years, a mass of 0.738 solar masses, a radius of 0.713 solar radii, and a temperature of 5010 K. Its reported mass and radius are smaller than the Sun's, and its temperature is cooler. One planet is known to orbit this host.
K2-110 b is a Neptune-like planet discovered by the transit method in 2017. It has a mass of 15.9 Earth masses and a radius of 2.59 Earth radii, both larger than Earth's. Its mean density is 5.03 g/cm³, 0.913 times Earth's. The planet completes one orbit every 13.9 days.
