Sign in to saveKepler-452b (sometimes quoted to be an Earth 2.0 or ''Earth's Cousin based on its characteristics; also known by its Kepler object of interest designation KOI-7016.01'') is a super-Earth exoplanet orbiting within the inner edge of the habitable zone of the sun-like star Kepler-452 and is the only planet in the system discovered by the Kepler space telescope. It is located about from Earth in the constellation of Cygnus.
AI overview
Kepler-452b is a super-Earth exoplanet orbiting a sun-like star in the constellation Cygnus, discovered by NASA's Kepler space telescope, and it resides in the habitable zone where liquid water could potentially exist. Its discovery matters because it represents one of the closest analogs to Earth found so far, offering scientists a key example of an Earth-sized world in a potentially habitable environment around a similar star.

Kepler-452b (sometimes quoted to be an Earth 2.0 or ''Earth's Cousin based on its characteristics; also known by its Kepler object of interest designation KOI-7016.01) is a super-Earth exoplanet orbiting within the inner edge of the habitable zone of the sun-like star Kepler-452 and is the only planet in the system discovered by the Kepler space telescope. It is located about from Earth in the constellation of Cygnus.
Kepler-452b orbits its star at a distance of from its host star (nearly the same distance as Earth from the Sun), with an orbital period of roughly 385 days, has a mass at least three times that of Earth, and has a radius of around 1.63 times that of Earth, or around 63% larger than earth in size. It is the first potentially rocky super-Earth planet discovered orbiting within the habitable zone of a very Sun-like star. However, it is unknown if it is entirely habitable, as it is receiving slightly more energy from its star than Earth and could be subjected to a runaway greenhouse effect.
