About this world
Kepler-1649 c is an Earth-sized planet orbiting Kepler-1649, a cool red dwarf 301 light-years from Earth. It is about 1.1 times the size of Earth. It completes an orbit every 19.5 days at 0.065 AU from its star, closer than Mercury is to the Sun.
Its equilibrium temperature is about 234 K (−39 °C), which places it in the conservative habitable zone: the band where liquid water could exist on a rocky surface. By the "cosmic shoreline", it has likely held on to an atmosphere.
It was discovered in 2020 by transit with Kepler. A planet crosses its star and dims it by a tiny, periodic fraction. Kepler-1649 has 2 known planets; the others are Kepler-1649 b.
