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.

What challenges do astronomers face when detecting exoplanets like Kepler 70b?

What can the existence of extremely hot planets tell us about the variety of planets in the universe?
