K2-146b is a Neptune-like exoplanet discovered in 2018 by the Kepler Space Telescope that orbits a low-mass M-type star in the constellation Cancer.[1][2] Its host star, K2-146, is orbited by another planet named K2-146c.[3] The planet orbits K2-146 at a distance of 0.0248 AU (3,710,000 km),[3] fifteen times closer than Mercury is to the Sun (0.3871 AU[4]). Thus, it orbits very rapidly, with one year lasting just 2.64 days (63 hours),[5] and is far too hot to be habitable, with an equilibrium temperature of 534 K (261 °C; 502 °F).[6]
