List of hottest exoplanets

This is a list of the hottest exoplanets so far discovered, specifically those with temperatures greater than 2500 K (2230 °C; 4040 °F) for exoplanets irradiated by a nearby star and greater than 2000 K (1730 °C; 3140 °F) for self-luminous exoplanets. For comparison, the hottest planet in the Solar System is Venus, with a temperature of 737 K (464 °C; 867 °F).

This is a dynamic list and may never be able to satisfy particular standards for completeness. You can help by adding missing items with reliable sources.

Methods for finding temperature:

• T_eff: Measured effective temperature.
• T_eq: The temperature of the planet has not been measured, so it is listed with the calculated equilibrium temperature.
