Kepler

Astronomy

A NASA satellite launched in 2009 March to search for extrasolar planets. It was placed into an Earth-trailing heliocentric orbit with a period of 372.5 days, in which the spacecraft slowly drifts away from Earth. Kepler monitored a field of over 150 000 main-sequence stars in Cygnus and Lyra with a 0.95-m Schmidt telescope, looking for dips in their light caused by the transit of planets, until 2013 May. In 2014 March an extended mission began called K2, studying additional areas of sky along the ecliptic. The mission ended in 2018 October when Kepler ran out of fuel, by when it had discovered over 2600 confirmed exoplanets.

Space Exploration

A NASA satellite designed to detect Earth-sized planets around other stars. Kepler’s first mission was to continuously monitor 150 000 main-sequence stars in a 10-degree-square patch of sky in the constellation Cygnus for four years. It carries a 0.95-m diameter telescope with a highly sensitive photometer that will detect changes in the stars' brightness due to planets passing in front of them. To detect an Earth-size planet, the photometer must be able to sense a drop in brightness of only 0.01 of a percent. Kepler launched on 7 March 2009. A mechanical failure in May 2013 brought an end to its its first mission. Its second mission (K2)—to search for transiting exoplanets—became fully operational in May 2014 and continued to operate until October 2018 when it ran out of fuel. As of March 2018, Kepler had found 2,342 confirmed planets around other stars.
