What is the composition of Venus' atmosphere?

Answer 1

As can be seen in the planetary data table below, Venus' atmosphere is nearly 100 times as massive as Earth's, and its thick cloud layers block the surface from view. It exerts a pressure of approximately 92 bars at the surface. Its composition is nearly all CO2:

CO2: 96.5%

N2: 3.5%

SO2: 0.015%

Ar: 0.007%

H2O: 0.002%

CO: 0.0017%

He: 0.0012%

Ne: 0.0007%
