Venus
Greenhouse effect. The same effect that keeps Earth warmer than if there would be no atmosphere: without an atmosphere, the average temperature on Earth would be below zero Celsius.
Immediate death Not necessarily immediately, don't forget that he would have a capsule and spacesuit to protect him for a while. How long would depend of the strength of the capsule. As the pressure of the atmosphere of Venus is equivalent of being a kilometre below the surface of the oceans. Then there is the heat, Venus is hotter than Mercury at 4600C, because of its thick atmosphere. So an Astronaut would survive, the question is 'For how long'.
Venus' atmosphere is composed mainly of carbon dioxide and a thick layer of sulfuric acid clouds, which can lead to temperatures exceeding 800 degrees Fahrenheit (427 degrees Celsius). The extreme heat and pressure on Venus would quickly burn your skin upon contact.
The visible spectrum of sunlight reflected from Titan would appear pale yellow or orange due to the presence of methane in its atmosphere, which absorbs and scatters shorter-wavelength light. The hazy atmosphere on Titan also contributes to the muted colors observed from space.
Due to the greenhouse effect.The thick atmosphere of Venus absorbs radiation from the Sun, but does not readily release it back into space.
The heat would make no difference, but the atmosphere would increase the weight.
CO2
Venus is very hot with poisonous gases in the atmosphere, Mars is very cold with a low atmospheric pressure.
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.
That would be Venus.
I think that would be Venus.
No. The atmosphere of Venus would kill you very quickly. At the surface, temperatures exceed 800 degrees Fahrenheit and pressure is more than 90 times that at sea level on Earth. The atmosphere itself is mostly carbon dioxide. So you would be simultaneously baked and crushed if you were to set foot on Venus.
Venus has an atmosphere that is extremely dense and composed mainly of carbon dioxide. The atmospheric pressure on Venus is about 92 times that of Earth's, which would crush a human due to the immense pressure.
A human would die of asphyxiation on Venus because Venus's atmosphere does not contain oxygen. The main component that makes up the atmosphere of Venus is Carbon Dioxide (CO2)- the by-product of human respiration. But regardless of whether or not theres oxygen on Venus the surface temperature is 900 Degrees F so if we were to stick a human there they would certainly burn to death before suffocation would even start.
Venus
Acually venus is the hottest planet because venus's atmosphere is composed mainly of co2. because of this venus's atmosphere has a extreme green house effect were all of the solar radiation is trapped in venus's atmosphere.
