The TESS mission observed a super hot planet, KELT-9 b. This gas-giant world, about 1.8 times bigger than Jupiter, receives 44,000 times more energy from its star than Earth does from the Sun. This makes the planet’s dayside temperature around 7,800 degrees F (4,300 C) — hotter than the surfaces of some stars. This intense heating also causes the planet’s atmosphere to stream away into space. Between July 18 and Sept. 11, 2019, as part of the mission’s yearlong campaign to observe the northern s

Observations from NASA's Transiting Exoplanet Survey Satellite (TESS) have revealed new details about the planet’s environment. The planet follows a close, polar orbit around a squashed star with different surface temperatures, factors that make peculiar seasons for KELT-9 b.
