Kelt 9B is an extremely hot planet, receiving 44,000 times more energy than Earth from its star. Its atmosphere boils away due to high temperatures. NASA's TESS satellite has observed Kelt 9B, revealing its unusual orbit and gravity darkening effects. The planet's orbit over the star's poles creates unique seasons, with rapid temperature changes causing wild winds. Scientists are using these observations to model Kelt 9B's atmosphere and gain insights into similar systems.
