Discovery status | Confirmed |
Kepler-445d is an exoplanet orbiting the red dwarf Kepler-445 every 8 days in the circumstellar habitable zone.[3] It has a surface temperature of 305 K (32 °C; 89 °F) making it suitable for life.[4] PHL has currently not assessed the planet for habitability.[5]
Physical characteristics
Kepler-445d is only slightly larger than the Earth, with a radius of 1.25 R⊕. According to PHL's calculators, the mass required for the planet to have the same density as the Earth is around 2 M⊕.[6]
