Does Mercury have a high surface temperature?
Does Mercury have a high surface temperature?
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).
What is the highest surface temperature of Mercury?
800 degrees Fahrenheit
According to NASA, the tiny world suffers the most extreme temperature range of any other planet in the solar system. The day side of the planet reaches temperatures of up to 800 degrees Fahrenheit (427 degrees Celsius). In contrast, the chilly night side can get as cold as minus 290 F (minus 180 C).
Why does Mercury have a high surface temperature?
Mercury’s orbital-rotational resonance ratio is 3:2. All other planets in our solar system have a ratio of 1:1. Therefore Mercury’s very long solar day, close proximity to the Sun and very thin atmosphere, all combine to produce the largest diurnal temperature spread in our solar system.
What is the surface temperature of Mercury on the side not facing the sun?
On the daylight side, the side of Mercury facing the sun, temperatures reach 500 degrees Celsius or 900 degrees Fahrenheit, hot enough to melt tin. On the night side, the side of the planet away from the sun, temperatures drop as low as -200 degrees Celsius, or -300 Fahrenheit, the temperature of liquid nitrogen.
What temperature is Mercury when facing the sun?
Why is the surface temperature on Venus?
Venus is so hot because it is surrounded by a very thick atmosphere which is about 100 times more massive than our atmosphere here on Earth. As sunlight passes through the atmosphere, it heats up the surface of Venus. The heat becomes trapped and builds up to extremely high temperatures.
Why does Venus have a higher surface temperature than Mars?
Planetary surface temperatures tend to get colder the farther a planet is from the Sun. Venus is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet.
