Background edit
The planet was found using data from the NASA Kepler Space Telescope, K2, and the Transiting Exoplanet Survey Satellite. K2-415b was discovered in February 2023.[2]
K2-415b is approximately 1.015 times the radius of Earth and is 7.5 times the mass of Earth. It does not orbit its star within its proposed habitable zone and orbits at a distance of around 0.027 AU and completes one orbit around its star every 4.018 days; because of this, the average surface temperature of K2-415b is estimated to be 400 K (260 °F; 127 °C).[3]
