Context from the literature
The list of exoplanets detected by the Kepler space telescope contains bodies with a wide variety of properties, with significant ranges in orbital distances, masses, radii, composition, habitability, and host star type. As of June 16 2023, the Kepler space telescope and its follow-up observations have detected 2,778 planets, including hot Jupiters, super-Earths, circumbinary planets, and planets located in the circumstellar habitable zones of their host stars. Kepler has detected over 3,601 unconfirmed planet candidates and 2,165 eclipsing binary stars.
