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.

Nov 8, 2024 · KELT-9b is a gas giant 2.8 times more massive than Jupiter, but only half as dense. Scientists would expect the planet to have a smaller radius, but the extreme radiation from its host star has caused the planet's atmosphere to puff up like a balloon.

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 6, 2017 · Astronomers have found the hottest known exoplanet, a world where temperatures exceed those on the surface of most stars. The Jupiter-like planet, known as KELT-9b, zips around its hot host...

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.

Jun 5, 2017 · Scientists have found one of the craziest exoplanets yet. It's a huge gas giant not unlike our Solar System's own Jupiter, but it travels around its star in just 1.5 days, with a surface hotter than most stars. The planet orbits a blazing star called KELT-9, …

Jun 5, 2017 · “KELT-9b” intrigues astronomers not just because of the unusual chemistry the heat is bound to create in its atmosphere, but also because of the opportunities it offers for more in-depth...

Aug 15, 2018 · For the first time ever, astronomers have found iron and titanium in the atmosphere of a planet outside the solar system. The exoplanet, named KELT-9b, is the hottest alien world ever discovered....
