The Atmosphere of Venus The atmosphere of Venus is mostly carbon dioxide, 96.5% by volume. Most of the remaining 3.5% is nitrogen. Early evidence pointed to the sulfuric acid content in the atmosphere, but we now know that that is a rather minor constituent of the atmosphere. The mass of the Venus atmosphere is about 90 times that of the Earth's atmosphere. 90% of the Earth's atmosphere is within 10 km of the surface, whereas you have to go to 50 km to capture 90% of the atmosphere of Venus. The clouds of Venus may extend from about 50 to 70 km and may be divided into three distinct layers.
Venus, the hottest planet in the solar system. Venus is the second closest planet to the Sun. Telescopes reveal little about the planet due to global cloud cover. Venus' mass and volume are quite similar to Earth's (Venus' mass is 81.5% of Earth's and its volume is 86% of Earth's).Its almost circular orbital period is 224.7 Earth days.A 0.76 albedo makes Venus the brightest planet, earning it the nickname 'the Morning Star'.enus' mass and volume are quite similar to Earth's (Venus' mass is 81.5% of Earth's and its volume is 86% of Earth's).
