How many planets has kepler found

But over more than nine years of operations the spacecraft opened worlds to us. What Did Kepler Teach Us? Celebrating the Space Telescope, 10 Years after Launch. It moved from planet candidate to false positive and back until scientists refined the data and took a new look.

Discovery Alert! There are thousands of known exoplanets - planets orbiting stars other than our Sun - but citizen scientists have helped discover one that has a rare quality.

On the evening of Thursday, Nov. After spending nine years in deep space and revealing that our galaxy contains more planets even than stars, NASA's Kepler space telescope has run out of fuel. NASA retires Kepler space telescope, passes planet-hunting torch. NASA is hosting a media teleconference on the status of the Kepler space telescope today. NASA will give an update on the Kepler space telescope today.

Meet the Kepler mission team. NASA woke up the Kepler space telescope and maneuvered it into a stable configuration to download its latest data with the least amount of fuel consumption. Latest on the Kepler spacecraft. Using the Hubble and Kepler space telescopes, astronomers have uncovered tantalizing evidence of what could be the first discovery of a moon orbiting a planet outside our solar system.

New moon? Astronomers find first evidence of a possible moon outside our solar system. NASA's Kepler space telescope, low on fuel, is placed in sleep mode. Kepler space telescope placed in sleep mode. Travelers to the nightside of exoplanet KeplerAb should pack an umbrella because they will be pelted with alien precipitation.

During Kepler's four-year primary mission, the telescope stared at about , stars simultaneously, watching for planetary transits. This work ended in May , when the second of Kepler's four orientation-maintaining reaction wheels failed. In , Kepler began K2, during which the craft observes a variety of cosmic objects and phenomena over shifting day "campaigns. Kepler's total tally represents about 70 percent of the roughly 3, known exoplanets.

And the Kepler count will continue to grow; nearly 3, planet "candidates" await confirmation by follow-up analysis or observation, and history suggests that most of these will end up being the real deal. But Kepler's observing days are drawing to a close. The spacecraft is extremely low on fuel and recently went into a "no fuel-use" sleep mode.

Mike Wall's book about the search for alien life, " Out There ," will be published on Nov. Follow him on Twitter michaeldwall. Follow us Spacedotcom or Facebook. Originally published on Space. On this page we have assembled statistics for various categories of confirmed exoplanets, TESS candidates, and Kepler candidates.

The Exoplanet Archive's collection of known exoplanets were discovered using a variety of methods, and many have been detected using multiple methods. The following tables show the number of planets contained within the Exoplanet Archive whose discovery can be attributed to a particular technique.

The criteria by which a planet is included in the Exoplanet Archive is described on our Exoplanet Criteria page. Clicking on a link returns a pre-filtered interactive table for that particular data set.
