In addition to being roughly Earth-sized and lying within its star's habitable zone, Kepler-452b is like Earth in some other ways. It orbits at a distance about 5% further from its star than the Earth is from the Sun. As a result, its year is almost the same length as ours, at roughly 385 days.

To date, more than 5,000 exoplanets have been discovered and are considered "confirmed" out of the billions in our galaxy alone. There are thousands of other "candidate" exoplanet detections that require further observations in order to say for sure whether or not the exoplanet is real.

Kepler-70 b is an exoplanet orbiting the star KOI-55, located about 3848.6 light-years (1180.0 pc) away from Solar System. Its discovery was publicly announced on 2011.

As of June 2021, a total of 59 potentially habitable exoplanets have been found.
