That's believed to be a byproduct of volcanism, though the atmosphere is mainly filled with carbon dioxide.
The atmosphere on Venus appears yellowish due to sulfur dioxide, which scatters light in the yellow part of the spectrum.
The name Venus (Greek form:Aphrodite) means the goddess of love and beauty in Rome. The planet is named after her because it is the brightest planet in the night sky. Venus has a very thick atmosphere and rotates the opposite way of all the other planets.
There are several differences between Earth and Venus. For one, Earth has water in all three states - gas, liquid, and solid - whereas Venus doesn't. Venus's thick, extensive cloud cover drops sulfur - filled acid rain on the landscape constantly. Lastly, Venus's atmosphere is about 98 times as dense as Earth's and contains much more carbon dioxide.
No. The atmosphere of Venus is mostly carbon dioxide with some nitrogen and trace amounts of other gasses.
Presuming you mean which planet has carbon dioxide as the primary component of its atmosphere, and features clouds of sulfur dioxide (or sulfuric acid), which would be Venus, second planet from the Sun (the next innermost planet from the sun compared with earth).
Venus has a very thick and acid filled atmosphere. The atmosphere of Venus is very dangerous to space probes. Over the years we have sent many probes to Venus but the corrosive acid and heavy atmosphere destroys them practically before they get to the surface!
Venus' atmosphere is primarily composed of carbon dioxide (96.5%) with traces of nitrogen and sulfur dioxide.
Venus' atmosphere is 96.5% carbon dioxide and 3.5% nitrogen. There are heavy clouds of sulfur dioxide and sulfuric acid. The runaway greenhouse effect that results causes the temperature to be 860 F, making Venus the hottest planet in the Solar System.
Venus and Jupiter are known to have atmospheres with poisonous gases. Venus's atmosphere is mostly made up of carbon dioxide and sulfur dioxide, while Jupiter's atmosphere contains ammonia and methane, among other toxic gases.
If by Oxygen you mean pure Oxygen molecules, then no, only possible trace amounts. However, there is massive amounts of Carbon Dioxide (95% of Venus's atmosphere) which can be fairly easily be converted into oxygen.
Mercury is much closer to the sun than Venus. It has less of an atmosphere, much higher temperatures, and a very short year. Venus has an very sulfur-rich atmosphere, cooler temperatures than Mercury, and a longer year than Mercury.
Venus has a thick atmosphere composed mainly of carbon dioxide (CO2), along with trace amounts of other gases like nitrogen and sulfur dioxide. This dense atmosphere creates a strong greenhouse effect that traps heat and leads to extremely high surface temperatures on Venus.
