Even though Mercury is closer to the Sun, Venus is the hottest planet in our solar system. Its thick atmosphere is full of the greenhouse gas carbon dioxide, and it has clouds of sulfuric acid. The atmosphere traps heat, making it feel like a furnace on the surface. It's so hot on Venus, the metal lead would melt.
Is Venus hotter than Mercury?
Venus has an atmosphere that is made of carbon dioxide, and it also has clouds of acid inside the atmosphere. This thick atmosphere makes the surface of Venus hotter than Mercury and hotter than all the other planets in our Solar System because the heat does not escape back into space.

Which planet is hottest and why?
Venus is actually the hottest planet in the solar system. On a hot day on Mercury, the temperature can rise to over 700 ºF. That's hot!
Why is Mars red?
Well, a lot of rocks on Mars are full of iron, and when they're exposed to the great outdoors, they 'oxidize' and turn reddish — the same way an old bike left out in the yard gets all rusty. When rusty dust from those rocks gets kicked up in the atmosphere, it makes the martian sky look pink.
How hot is Jupiter?
It is estimated that the temperature of the cloud tops are about -280 degrees F. Overall, Jupiter's average temperature is -238 degrees F. Since Jupiter is only tilted slightly more then 3 degrees on its axis, seasonal fluctuations are minimal.
Is Uranus the hottest planet?
The temperature of Uranus averages minus 320 degrees Fahrenheit (-195 degrees Celsius), according to NASA. (opens in new tab) Uranus holds the record for the coldest temperature (opens in new tab) ever measured in the solar system — minus 371.56 degrees F (minus 224.2 degrees C).
What planet is the darkest?
TrES-2b Kepler has found the darkest known planet in universe–a Jupiter-sized exoplanet some 750 light-years away that is so black that it reflects just one percent of the light that reaches it. TrES-2b is so black that it's darker than coal, or any other planet or moon that we've yet discovered.
Can you breathe on Mars?
Mars does have an atmosphere, but it is about 100 times thinner than Earth's atmosphere and it has very little oxygen. The atmosphere on Mars is made up of mainly carbon dioxide. An astronaut on Mars would not be able to breathe the Martian air and would need a spacesuit with oxygen to work outdoors.
Can humans live on Jupiter?
Jupiter's environment is probably not conducive to life as we know it. The temperatures, pressures, and materials that characterize this planet are most likely too extreme and volatile for organisms to adapt to.
