What is the Mercury’s weather like?
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).
Which planet has weather like Earth?
Atmosphere and Weather: Venus has a thick atmosphere made up almost entirely of carbon dioxide. It also exerts a pressure 92 times higher than the earth’s, resulting in a pressure-cooker environment. Venus is covered by dense clouds made up primarily of sulfuric acid.
Does Mercury have rain?
Since Mercury has hardly any atmosphere, it does not have weather like storms, clouds, winds or rain. Its surface temperature can reach 801 Fahrenheit during the day (because it is so close to the Sun) and can drop to -279 Fahrenheit at night (because there is no atmosphere to trap the daytime heat).
What’s hotter Venus or Mercury?
The carbon dioxide traps most of the heat from the Sun. The cloud layers also act as a blanket. The result is a “runaway greenhouse effect” that has caused the planet’s temperature to soar to 465°C, hot enough to melt lead. This means that Venus is even hotter than Mercury.
Why does Mercury not have weather?
Due to the tenuous atmosphere, Mercury really has no weather to speak of other than wild fluctuations in temperature. … 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.
