Kepler-452b: An Earth-like World in the Habitable Zone of a Sun-like Star

To the point

Kepler-452b is an Earth-like exoplanet discovered by NASA's Kepler spacecraft in 2015 that orbits the Sun-like star Kepler-452 in the habitable zone about 1,400 light-years away, is roughly 1.6 times Earth's diameter and about five times as massive, and while models allow for a nitrogen-rich atmosphere and potential liquid water, many key properties such as its atmosphere, surface conditions, magnetic field, and long-term stability remain unknown.
