You probably know that Mercury is the closest planet to the sun by far, so shouldn’t it also be the hottest planet in the solar system?
Well, one would think so, but that isn’t the case.
The planet Venus (the second planet from the sun) is actually hotter than any of the other planets, Mercury included.
That’s right, with temps as high as 870 degrees Fahrenheit, Venus is actually hotter than Mercury which “only” gets as hot as 800 degrees.
The reason Venus is hotter than Mercury even though it’s farther from the sun is because Venus has a very thick atmosphere.
That atmospheric “cover” traps much of the heat Venus receives from the sun and prevents it from escaping back into space.
This phenomenon is commonly referred to as the “greenhouse effect”.
Truth be told, you’ve probably experienced the greenhouse effect on a very personal scale…
