New observations from NASA’s Transiting Exoplanet Survey Satellite (TESS) have enabled astronomers to improve their understanding of the bizarre environment of KELT-9b, an ultrahot Jupiter exoplanet transiting the rapidly rotating early-A-type star KELT-9.

KELT-9b belongs to a family called ultrahot Jupiters, incredibly hot giant exoplanets that orbit very close to their parent stars.

Discovered in 2017, the planet is a gas giant about 1.8 times bigger than Jupiter, with 2.9 times its mass.

It orbits its host star, KELT-9, once every 36 hours on an orbit that carries it almost directly above both of the star’s poles.

At around 9,900 degrees Celsius (17,850 degrees Fahrenheit), the host star is at the dividing line between stars of type A and B.

Also known as HD 195689, the star is about 650 light-years away in the constellation of Cygnus.

It’s about twice the size of our Sun and averages about 56% hotter. But it spins 38 times faster than the Sun, completing a full rotation in just 16 hours.
