This is a list of the hottest exoplanets so far discovered, specifically those with temperatures greater than 2,500
K (2,230 °C; 4,040 °F). For comparison, the hottest planet in the
Solar System is
Venus, with a temperature of 737 K (464 °C; 867 °F).
In this
tidally locked planet where winds move 18,000 km/h, molten iron rains from the sky due to daytime temperatures exceeding 2,400 °C (2,670 K).[15][16]
Higher published temperature of 3800 K[22] might be connected to later identified 'UV-Optical Emission of AB Aur b' being 'Consistent with Scattered Stellar Light'.[23]
