The Hottest Exoplanets in the Universe

The video explores the fascination with extreme planets, focusing on three ultra hot worlds: TOI-2109b, Kelt-9b, and the hypothetical Kepler 70b. TOI-2109b is a gas giant close to its star, with a year lasting only 16 hours. Kelt-9b, the hottest known planet, orbits a star twice as hot as our sun, leading to extreme temperatures that could melt any material. Kepler 70b, though likely non-existent, was thought to be even hotter. These planets, while uninhabitable, showcase the diversity of worlds in our galaxy.
