Kepler-452b

Kepler-452b is an exoplanet (a planet outside of our solar system) that was discovered by NASA’s Kepler spacecraft in 2015. It is located in the habitable zone of its star, Kepler-452, which means that it is at a distance from its star where temperatures could potentially allow liquid water to exist on its surface.

Kepler-452b is often referred to as an “Earth twin” or “Earth 2.0” because it is the most Earth-like exoplanet that has been discovered to date. It has a similar size to Earth, with a radius that is about 60% larger than Earth’s, and it orbits a star that is very similar to our sun. Its orbital period is about 385 days, which is only slightly longer than Earth’s.

However, it is important to note that we do not know if Kepler-452b has an atmosphere or if it has the conditions necessary to support life. Further observations and research will be necessary to determine if this planet could potentially be habitable.
