The main difference is that Venus has a dense atmosphere, while Mercury has none. The usually accepted theory is that something in Venus' atmosphere caused a runaway greenhouse effect.

How is Venus different from Jupiter?

The diameter of Venus is only 12,103 km, while the diameter of Jupiter is 142,984 km. And so when you compare the two planets, Jupiter is 11.8 times bigger than Venus.


Why is it difficult for spacecraft to study Venus?

It is difficult because Venus has a thick atmosphere of methane. The atmosphere is so thick when a NASA probe tried to enter the thick atmosphere it crumbled to piece's. So that's why its hard.


How hot can Venus get in its atmosphere?

Well hello there, friend! Venus can get surprisingly hot from all those layers in its atmosphere trapping heat. Temperatures on Venus can reach up to about 900 degrees Fahrenheit (about 475 degrees Celsius)! Isn't that just incredible? Just like how the best things in life sometimes come from unexpected places.


Why does venus have higher surface temperatures than mercury even though venus is farther from the sun?

Because Venus is closer to the sun than Earth is, it receives more solar energy than Earth does. Much of this radiation is reflected by Venus's clouds, but some radiation reaches the surface and is later given off as heat. The carbon dioxide in Venus's atmosphere traps heat so well that Venus has the hottest surface among the planets. This trapping of heat by the atmosphere is called the greenhouse effect.


Which planet's atmosphere is so heavy and thick that it could crush a human?

Venus has an atmosphere that is extremely dense and composed primarily of carbon dioxide, with pressure at the surface about 92 times that of Earth's. The atmospheric pressure and high temperatures on Venus would indeed crush and incinerate a human.

Why is Venus surface temperatures so high?

because its closer to the sun


Why did temperatures on Venus rise so high because of the greenhouse effect?

Temperatures on Venus rose so high because of the greenhouse effect, which is caused by the thick atmosphere trapping heat from the sun. The atmosphere on Venus is mostly made up of carbon dioxide, which absorbs and retains heat, leading to extreme temperatures on the planet.


Why does earth a liquid water supply an Venus does not?

Venus is closer to the sun, so it's hotter there. Water needs to stay below 100 deg C to remain a liquid, and Venus is hotter than that.


What is the capital of Venus?

Venus is an uninhabited planet.No people, no need for cities, thus...no capital.


Why did Venus become so hot?

Venus became hot due to its thick atmosphere trapping heat from the sun, creating a greenhouse effect that raises temperatures to extreme levels.


How is Venus's different to other objects?

VENUS IS DIFFERENT FROM OTHER OBJECTS BECAUSE VENUS ROTATES IN THE OPPISITE DIRECTION WHILE ITS ORBITING THE SUN.VENUS IS ALSO DIFFERENT BECAUSE ITS CLOUDS ARE FULL OF SULPHURIC ACID AND VENUS IS SO HOT THAT IT CAN MELT LEAD. VENUS IS KNOWN AS EARTHS UGLY SISTER BECAUSE THEY BOTH STARTED OFF THE SAME BUT VENUS'S OCEANS EVAPORATED BECAUSE IT STARTED GETTING SO HOT .


Is there safe gravity range on venus?

The strength of gravity on the surface of Venus is about 91% of what it is on Earth, so the gravity there would be quite comfortable. Unfortunately the surface temperatures and pressures produced by the atmosphere of Venus would kill a human very quickly.


Is Venus's temperature high or low?

Venus's temperature is so high that it is impossible to have life on it. Venus's normal temperature is around 430F degrees to 900F degrees. That's really hot , because having temperatures so high all the water evaporates, that why it can't support life.


How many robots were on venus and what is there name?

There have been no known robots on Venus. Due to the extreme environment on the planet, such as high temperatures and pressure, it is difficult to send robots there.


How do temperatures on the moon different from the earth?

Temperatures vary so much because the moon does not have an atmosphere.


Is there mining on Venus If so where is Exxon Mobil?

No. We currently to not have the technology for interplanetary mining. All mining takes place on Earth. Venus is particularly inhospitable due to extremely high pressures and temperatures at the surface, so if we were to start mining offworld, we would probably go to Mars or to asteroids instead of Venus.


Are you sure humans can live on Venus'?

This is absolutely incorrect. Venus's carbon atmosphere is so thick and dense that temperatures on venus reach 464 degrees celcius, and many, many volcanic eruptions are occurring every second on venus. Since there is so much carbon dioxide in the atmosphere, it would be impossible for humans to breathe. Those are just some obvious reasons why venus is inhabitable to humans.
