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).
24 kwi 2017 · That honor goes to Venus, which experiences an average surface temperature of 750 K (477 °C; 890 °F). Not only that, but Mercury is also cold enough in some regions to maintain water in ice...
30 lis 2016 · 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). It never rises above 180 K at the poles, due to the absence of an atmosphere and a steep temperature gradient between the equator and the poles.
15 lut 2022 · 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.
11 sty 2024 · 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 ...
Mercury, the closest planet to the Sun, has surface temperatures of up to 465 ° C (869 ° F), but Venus is hotter. Like our Moon, Mercury has water ice in permanently shadowed craters at the poles. Mercury has a particularly large core and scientists aren't sure why.
