What is the average daytime and nighttime temperature on Mercury?
Here's an answer, but it's not exactly what you want :
Daytime maximum temperature : about 430 degrees Celsius.
Night minimum temperature : about minus 170 degrees Celsius.
Mercury, but it has a very thin and light atmosphere made of helium and sodium. Mercury's daytime temperature is 400oC and the nighttime temperature is -200oC. All planets have very different temperatures at the surface. Mercury's Maximum Temperature 465°C (870°F) Mercury's Minimum Temperature -184°C (-300°F) Venus' Average Temperature 449°C (850°F) Earth's Average Temperature 7.2°C (45°F) Mars's Maximum Temperature 36°C (98°F) Mars's Minimum Temperature -123°C (-190°F) Jupiter's Average Temperature -153°C (-244°F) Saturn's Average Temperature -184°C (-300°F)…
