Relative dating planets
Using the transit method, Kepler has detected 2,740 candidates.
Using various analysis techniques, ground telescopes and other space assets, 122 planets have been confirmed.
Kepler-62f is only 40 percent larger than Earth, making it the exoplanet closest to the size of our planet known in the habitable zone of another star. Kepler-62e, orbits on the inner edge of the habitable zone and is roughly 60 percent larger than Earth.
The third planet, Kepler-69c, is 70 percent larger than the size of Earth, and orbits in the habitable zone of a star similar to our Sun.
Ames is responsible for Kepler's ground system development, mission operations, and science data analysis. in Boulder, Colo., developed the Kepler flight system and supports mission operations with the Laboratory for Atmospheric and Space Physics at the University of Colorado in Boulder.
NASA's Jet Propulsion Laboratory in Pasadena, Calif., managed Kepler mission development. The Space Telescope Science Institute in Baltimore archives, hosts and distributes Kepler science data.
When a planet candidate transits, or passes in front of the star from the spacecraft's vantage point, a percentage of light from the star is blocked.
Kepler-62b, Kepler-62c and Kepler-62d, orbit every five, 12, and 18 days, respectively, making them very hot and inhospitable for life as we know it.Kepler-62f, with an orbital period of 267 days, was later found by Eric Agol, associate professor of astronomy at the University of Washington and co-author of a paper on the discoveries published in the journal Science [
