* Surface Temperature: Venus has the hottest surface temperature of any planet in our solar system, reaching a scorching 867 degrees Fahrenheit (464 degrees Celsius). This is due to a runaway greenhouse effect.
* Atmospheric Temperature: If we consider atmospheric temperature, the upper atmospheres of gas giants like Jupiter and Saturn can reach much higher temperatures due to intense radiation from their cores.
* Internal Temperature: The cores of gas giants like Jupiter and Saturn are incredibly hot, reaching tens of thousands of degrees Celsius.
Therefore, the answer to your question depends on what you mean by "warmest":
* Hottest Surface: Venus
* Hottest Atmosphere: Jupiter and Saturn
* Hottest Core: Jupiter and Saturn
It's important to note that these are just the average temperatures. There can be significant variation in temperature depending on location and time of day on a planet.
