NASA's Kepler Mission By the Numbers

Kepler was in orbit 9.6 years, used 3.12 gallons of fuel, observed 530,506 stars and led to the discovery of 2,662 planets.

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.

A wide shot shows the planet WASP-18 b rapidly orbiting its star, WASP-18. Time slows down and the camera zooms in on the planet. The planet starts to slowly move behind its star. An animated plot, displaying the eclipse data, is seen on the right side of the screen. It shows the light dipping as the planet passes behind the star. The planet continues to be eclipsed by its star on the left side of the screen. The planet has now been fully eclipsed by its star.
