About this world
Kepler-1606 b is a sub-Neptune orbiting Kepler-1606, a yellow, Sun-like star 2.71 thousand light-years from Earth. It is about 2.1 times the size of Earth. It completes an orbit every 196 days at 0.64 AU from its star.
Its equilibrium temperature is about 324 K (51 °C), which places it in the optimistic 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 2016 by transit with Kepler. A planet crosses its star and dims it by a tiny, periodic fraction.
