Can you live on venuse?
- But while we can't live on Venus , we could live above it. About 50 kilometres above the surface, the pressure and temperature is similar to that on Earth. All we'd need would be breathing suits to survive the sulphuric acid. Theoretically, humans could live on floating cities here.
Why is Venus hotter than Mercury?
- Venus is hotter than Mercury because of its thick atmosphere. According to NASA, Venus' atmosphere is 96 percent carbon dioxide, which holds in heat. Mercury has a very thin atmosphere that does not keep heat on the planet. The thick layer of carbon dioxide that surrounds Venus acts as a greenhouse.
Why is the atmospheric pressure so high on Venus?
- So the reason Venus has a high surface temperature is not because of the high pressure. The reason it has a high pressure is because of the high temperature and density. We can illustrate this by considering the Earth. Atmospheric pressure at sea level is 105 Pa. Atmospheric density at sea level is about 1.2 kg m-3.
