Coldest:
* Uranus: -224°C (-371°F) - This ice giant is incredibly cold due to its distance from the Sun and its tilted axis.
* Neptune: -214°C (-353°F) - Similar to Uranus, Neptune's distance and internal heat contribute to its frigid temperatures.
* Saturn: -178°C (-288°F) - Saturn's vast ring system and thick atmosphere contribute to its chilly surface.
* Jupiter: -145°C (-234°F) - This gas giant, while having a hot core, experiences incredibly cold temperatures at its cloud tops.
Moderate:
* Mars: -63°C (-81°F) - Mars is known for its frigid, thin atmosphere and dusty surface.
* Earth: 15°C (59°F) - Earth's average temperature is comfortable thanks to its atmosphere and distance from the Sun.
Hottest:
* Venus: 464°C (867°F) - Venus has a runaway greenhouse effect, trapping heat in its thick atmosphere and making it the hottest planet.
* Mercury: 167°C (333°F) - Mercury, despite being closest to the Sun, doesn't have a thick atmosphere to trap heat. Its temperature fluctuates greatly between day and night.
Important Notes:
* Surface Temperature: The temperatures listed above are average surface temperatures. The actual temperature of a planet can vary depending on its location, time of day, and other factors.
* Gas Giants: For gas giants like Jupiter and Saturn, the temperature is measured at the top of their cloud layers. Their internal temperatures are much hotter.
