# List of hottest exoplanets

This is a list of the hottest exoplanets so far discovered, specifically those with temperatures greater than 2,500K(2,230°C; 4,040°F) for exoplanets irradiated by a nearby star and greater than 2,000K(1,730°C; 3,140°F) for self-luminous exoplanets. For comparison, the hottest planet in the Solar System is Venus, with a temperature of 737K (464°C; 867°F).

## List of hottest exoplanets irradiated by a nearby star

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.
