Kepler-445d
Kepler-445d is an exoplanet orbiting the red dwarf Kepler-445 every 8 days possibly in the circumstellar habitable zone.[3] It has an equilibrium temperature of 305 K (32 °C; 89 °F).[2] PHL does not consider this planet potentially habitable.[4]

Physical characteristics
Kepler-445d is only slightly larger than the Earth, with a radius of 1.33 R🜨. According to PHL's calculators, the mass required for the planet to have the same density as the Earth is around 2 M🜨.[5]
