The Kepler space telescope is a defunct space telescope launched by NASA in 2009 [5] to discover Earth-sized planets orbiting other stars. [ 6 ] [ 7 ] Named after astronomer Johannes Kepler , [ 8 ] the spacecraft was launched into an Earth-trailing heliocentric orbit .
An artist's rendition of Kepler-62f, a potentially habitable exoplanet discovered using data transmitted by the Kepler space telescope. 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.

The time has finally come to say goodbye to Kepler, the spacecraft that exceeded expectations throughout its mission and has so far confirmed more than 2,600 planets outside of our solar system.
NASA's Kepler space telescope spent its almost-decade in space searching for distant worlds never before seen by mankind. It found plenty, but some discoveries were easier to verify than others ...
It was discovered by NASA's Kepler Space Telescope in December 2011 and was the first known transiting planet to orbit within the habitable zone of a Sun-like star, where liquid water could exist on the planet's surface. [4] Kepler-22 is too dim to be seen with the naked eye. Kepler-22b's radius is roughly twice that of Earth. [5]
NASA's Kepler Space Telescope has been hard at work scanning the universe for planetary bodies and has now confirmed a whopping 104 of them outside our solar system as part of its K2 mission.
The planet was discovered in 2015 by the Kepler space telescope, [86] [87] [88] and its existence was later confirmed with the Spitzer Space Telescope and through Doppler velocity techniques. [58] Analyses of the transits ruled out that they were caused by unseen companion stars, [88] by multiple planets or systematic errors of the observations ...
