Why is Venus hotter than Mercury?
Venus is hotter than Mercury because Venus has a thicker atmosphere than Mercury. Venus’s thick atmosphere traps the planet’s heat from the sun, making it hot enough to melt lead.
What are the similarities and differences between Venus and Mercury?
Mercury has almost no atmosphere, whereas the atmosphere of Venus is thicker. The heat from the sun will quickly be radiated back to space for the case of Mercury; however, Venus will tend to trap the heat resulting in very high temperatures on its surface.
Why is Mercury the 2nd hottest planet?
This thin exosphere means that the temperature on the planet Mercury can vary drastically, from over 400°c at one point to as cold as -180°c on the dark side of the planet. So, it’s clear to see why Mercury’s lack of atmosphere has left it as the second hottest planet as opposed to being the first.
What is the surface temperature of Venus?
Venus is an exception because its dense atmosphere acts as a greenhouse and heats the surface to above the melting point of lead, about 880 degrees Fahrenheit (471 degrees Celsius).
Why Venus is much hotter than 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.
Is Mercury the hottest planet?
