Mercury's surface temperatures are both extremely hot and cold. Because the planet is so close to the Sun, day temperatures can reach highs of 800°F (430°C). Without an atmosphere to retain that heat at night, temperatures can dip as low as -290°F (-180°C).
The planet has an average temperature of 332 F (167 C). These variations are relatively long-lived. Scientists once thought that Mercury kept a single side perpetually facing the sun, in...
The surface temperature of Mercury ranges from 100 to 700 K (−173 to 427 °C; −280 to 800 °F). [79] It never rises above 180 K at the poles, [15] due to the absence of an atmosphere and a steep temperature gradient between the equator and the poles.
Mercury rotates slowly and has a thin atmosphere, and consequently, the night-side temperature can be more than 1,000 degrees Fahrenheit lower than the day-side temperature. It can be as cold as -290°F (-179°C) on Mercury at night.
What temperature is planet Mercury? Minus 292 degrees Fahrenheit (180 degrees Celsius) at night to 986 degrees Fahrenheit (530 degrees Celsius), the maximum during the day. What color is...
Two locations on Mercury’s equator are called hot poles, and surface temperatures there can exceed 700 kelvins (K; 800 °F, 430 °C). Surface temperatures drop to about 90 K (−300 °F, −180 °C) during Mercury’s long nights before sunrise.
Surface pressure: <~5 x 10-15 bar (0.005 picobar) Average temperature: 440 K (167 C) (590-725 K, sunward side) Total mass of atmosphere: <~10000 kg Atmospheric composition (Column abundances in 10 6 per cm 2): Sodium 12,000-200,000; Magnesium 100,000; Oxygen <40,000; Hydrogen 5000, Potassium 800-1300, Calcium 300-1000; Iron <300; Aluminum 15 ...
How hot is Mercury? Since Mercury is the closest planet to the Sun, spins slowly, and does not have much of an atmosphere to trap heat, its temperature varies greatly. Mercury's temperatures can go between -279 Fahrenheit (-173 Celsius) at night to 801 Fahrenheit (427 Celsius) during the day.
What is the Temperature on Mercury? Mercury is hottest during the day when the maximum temperature reaches 427°C or 800°F. It is coldest during the night when the temperatures dip as low as -173°C or -280°F.
Whereas the side that faces the Sun can reach temperatures of up to 700 K (427° C; 800 °F), the side in shadow dips down to 100 K (-173° C: -279 °F). Despite its extreme highs in temperature,...
