Atmosphere of Venus Atmosphere of Venus Cloud structure in Venus' atmosphere in 1979, revealed by ultraviolet observations from Pioneer Venus Orbiter General information [1] Height 250 km Average surface pressure (92 bar or) 9.2 MPa Mass 4.8 × 10 20 kg Composition [1] [2] Carbon dioxide 96.5 % Nitrogen 3.5 % Sulfur dioxide 150 ppm Argon 70 ppm Water vapor 20 ppm Carbon monoxide 17 ppm Helium 12 ppm Neon 7 ppm Hydrogen chloride 0.1–0.6 ppm Hydrogen fluoride 0.001–0.005 p pm The atmosphere of Venus is much denser and hotter than that of Earth . The temperature at the surface is 740 K (467°C, 872°F), while the pressure is 93 bar . [1] The Venusian atmosphere supports opaque clouds made of sulfuric acid , making optical Earth-based and orbital observation of the surface impossible. Information about the topography has been obtained exclusively by radar imaging . [1] The main atmospheric gases are carbon dioxide and nitrogen . Other chemical compounds are present only in trace amounts.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
