During 9.6 years in orbit, the Kepler space telescope observed more than half a million stars and discovered more than 2,600 planets. See the mission by the numbers.
NASA's Kepler Mission By the Numbers
NASA Associate Administrator Thomas Zurbuchen and TESS Project Scientist Padi Boyd discuss Kepler's legacy, the search for life and the big question: Are we alone?
Next Steps in the Search for Life
The stars TESS studies are 30 to 100 times brighter than those the Kepler mission and K2 follow-up surveyed, enabling far easier follow-up observations with both ground-based and space-based telesc...

NASA's Kepler mission revealed that there are more planets than stars in our galaxy. It opened our eyes to diverse worlds – some entirely unlike planets found in our solar system.
Kepler's Science Results
The Kepler space telescope will remain for decades in orbit around the Sun, weaving in and out of Earth’s orbital path.
NASA's Kepler Space Telescope: Final Orbit
Launched in March 2009, NASA’s first planet-hunter confirmed more than 2,600 planets beyond our solar system. "Many stars have planets. A lot of these planets are Earth-sized. That's Kepler's legac...
