KELT-18b
KELT-18b is a hot Jupiter orbiting the F-type main sequence star KELT-18 approximately 1,058 light years away in the northern circumpolar constellation Ursa Major. The planet was discovered using the transit method, and was announced in June 2017. Discovery KELT-18b was discovered in 2017 by scientists using the KELTNorth telescope at the Winer Observatory. The paper states that this planet is the most "inflated" of its type due to its low mass, density, and high radius. Properties KELT-18b has 1.18 times Jupiter mass, Jupiter's mass, and is 57% larger than Jupiter. Despite the high mass, its density is lower than Saturn's, and has a high Planetary equilibrium temperature, equilibrium temperature of 2,085 Kelvin, K due to orbiting close to a hot star. The planet orbits at a distance 10 times closer than Mercury (planet), Mercury's in almost 3 days.

Kilodegree Extremely Little Telescope
The Kilodegree Extremely Little Telescope (or KELT) is an astronomical observation system formed by two robotic telescopes that are conducting a survey for transiting exoplanets around bright stars. The project is jointly administered by members of Ohio State University Department of Astronomy, the Vanderbilt University Department of Physics and Astronomy Astronomy Group, the Lehigh University Department of Physics, and the South African Astronomical Observatory (SAAO). KELT Telescopes KELT consists of two telescopes, KELT-North in Arizona in the United States, and KELT-South at the SAAO observing station near Sutherland, South Africa. Each KELT telescope consists of a wide field (26 degrees by 26 degrees) medium format telephoto lens with a 4.2 cm aperture, mounted in front of a 4k x 4k Apogee CCD. Each can also be equipped with an alternative narrower field (10.8 degrees by 10.8 degrees) lens with a 7.1 cm aperture for a narrow angle campaign mode. KELT-North u ...
