KELT-9b is an exoplanet and ultra-hot Jupiter that orbits the late B-type/early A-type star KELT-9, [4] located about 670 light-years from Earth. [4] Detected using the Kilodegree Extremely Little Telescope , the discovery of KELT-9b was announced in 2016.

Mar 28, 2025 · KELT-9 b is a gas giant exoplanet that orbits a B-type star. Its mass is 2.88 Jupiters, it takes 1.5 days to complete one orbit of its star, and is 0.03462 AU from its star. Its discovery was announced in 2017.

Jan 24, 2020 · Called KELT-9b, the planet is an ultra-hot Jupiter, one of several varieties of exoplanets — planets around other stars — found in our galaxy. It weighs in at nearly three times the mass of our own Jupiter and orbits a star some 670 light-years away.

Jun 5, 2017 · With a dayside temperature of more than 7,800 degrees Fahrenheit (4,600 Kelvin), KELT-9b is a planet that is hotter than most stars. But its blue A-type star, called KELT-9, is even hotter– in fact, it is probably unraveling the planet through evaporation.

Jan 28, 2020 · One such planet, KELT-9b, is an ultrahot Jupiter that resides 670 light-years from Earth. It weighs about three times the mass of Jupiter and boasts surface temperatures of 7,800 degrees...

Jun 5, 2017 · KELT-9 is about twice the mass, size, and temperature of our Sun and, sizzling at 9900°C, is the hottest star known to host a transiting exoplanet. If a naked-eye observer could see KELT-9 from...

Jun 5, 2017 · Gaudi and his team calculated KELT-9b to be roughly 3,777 degrees Celsius (6,830 degrees Fahrenheit) on the dark side and 4327 degrees C (7,820 degrees F) on the star-exposed side. This...

Jun 6, 2017 · KELT-9b is a gas giant 2.8 times more massive than Jupiter but only half as dense. The planet runs a close orbit to KELT-9, the hottest, most massive and brightest star yet found to host a transiting giant planet.

Nov 21, 2022 · KELT-9b is an ultra-hot Jupiter observed to be undergoing extreme mass-loss. Its A0-type host star has a radiative envelope, which makes its surface layers prone to retaining recently accreted material.

Aug 18, 2018 · KELT-9b is a giant gas world like Jupiter, the largest planet in our solar system. But it's way bigger—it has three times the mass and twice the diameter of Jupiter—and it orbits...
