The Secrets of the Universe | The Hottest Planet Ever Found @TheSecretsoftheUniverse | Uploaded April 2023 | Updated October 2024, 4 days ago.
The hottest planet we have ever discovered is Kelt-9b, located about 670 light-years away. It's 2.8 times more massive than Jupiter, and its surface temperature is about 4300° C or 7800° F, hotter than most stars in the universe. Its atmosphere contains iron vapor, which can be detected through spectroscopy. This means that the planet's atmosphere is so hot that iron is not just melted but actually turned into gas. Kelt 9b lies quite close to its host star, and its orbital period lasts just 1.5 days. Because of tidal locking, one side faces the star while the other is always in darkness. The planet's atmosphere is constantly bombarded with intense ultraviolet radiation, causing it to shed a tail of evaporated planetary material like a comet. Discoveries like Kelt 9b remind us of the incredible diversity of worlds beyond our solar system.
