If it's 800 degrees on Venus, and Venus is the second planet from the sun, why isn't it that hot on earth?

Question

Venus is the second planet from the sun, and Earth is the third planet fom the sun, on Venus it's like 800 degrees and here maybe on a good day get to 100-120 degrees if that.

Answer 1

Greenhouse effect gone wild!

Seriously though, Venus' atmosphere is 90+ times as dense as Earth's and loaded with carbon dioxide. This means that as the Suns shines on Venus, substantially more heat remains trapped in the atmosphere rather than radiating away into space.

Answer 2

We are on a science forum here, so let’s talk centrigrade – Venus surface is about 450C. That only sounds a lot in respect of what life can withstand, which is a very tiny part of the temperature band. In the scheme of the universe, where temperatures go from minus270 to 10s of millions of degrees, Venus is not much hotter than Earth.

However, it owes its life-unfriendly temperature to its massive atmosphere that traps the sun’s heat. If the Earth had the same atmosphere, we wouldn’t be here, but it would be a little less hot than Venus.

Answer 3

Venus has a thicker atmosphere with more green house gasses. Mars is colder than the earth so the cosmos is as it should be.

Hopefully global warming won't take us up close to the temperature of Venus.

Answer 4

the difference with venus is, that it has an extremly dense carbon-dioxide atmosphere.
this keeps heat radiation trapped within the atmosphere, where on earth a good portion of that radiation is reflected back into space

Answer 5

The energy is inverse as the square of the distance . It is not linear.

Answer 6

Sweety, If you get to close to the fireplace it gets hot. If you get to far, it gets cold.

Answer 7

We still have an atmosphere!

Answer 8

I don't know!
