Kepler-1652 b

Kepler-1652b (also known by its Kepler Objects of Interest designation KOI-2626.01) is a super-Earth exoplanet, orbiting within the habitable zone of the red dwarf Kepler-1652 about 822 light-years away in the Cygnus constellation. Discovered by NASA's Kepler spacecraft, Kepler-1652b was first announced as a candidate in 2013, but wasn't validated until four years later in 2017. It is a potential super-Earth with 160% Earth's radius. The planet orbits well within the habitable zone of its system, the region where liquid water can exist on a planet's surface. The planet is an eyeball planet candidate.

==Characteristics== ===Mass, radius, and temperature=== Kepler-1652b, like almost all of Kepler's known exoplanets, was found with the transit method, where a planet blocks a tiny fraction of its host star's light when it passed between the star and Earth's line of sight. As a result, the only well-established parameter is its radius. Based on the size of the star and the amount of light blocked, Kepler-1652b has a radius of 1.60 , within the super-Earth range between the sizes of Earth and the ice giants Uranus and Neptune. Usually, the transition between rocky Super-Earths and gaseous Mini-Neptunes is expected to be at 1.6 , which would suggest that Kepler-1652b may be a small ice giant or ocean planet. Kepler-1652b has a planetary equilibrium temperature of , similar to Earth's at .
