KELT (Kilodegree Extremely Little Telescope) is a pair of automated (robotic) telescopes to search for transiting planets over the whole sky covering magnitude range of 8 to 10. The telescopes have a 4.2 cm aperture and a field of view of 26 degrees by 26 degrees, with a 4k × 4k CCD. They are collecting a large database of transients, covering most of the sky.
KELT-North, in operation since 2005, is at Winer Observatory in Arizona. KELT-South began operation in 2009, in South Africa.
As of 2019, 20 planet discoveries are claimed.
