Planetary system
Kepler-445b, c, and d orbit Kepler-445 every 3, 5, and 8 days, and have equilibrium temperatures of 401 K, 341 K, and 305 K, respectively. With a radius of 2.72 times that of Earth, Kepler-445c is likely a mini-Neptune with a volatile-rich composition, and has been compared to GJ 1214 b. Kepler-445d is only slightly larger than the Earth, with a radius of.
