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.
