Venus is often called Earth's "Sister Planet" because of all the things they have in common. They are comparable in size, have similar compositions, and both orbit within the Sun's habitable zone. But beyond that, there are some notable differences that makes Venus a molten hellhole, and about the last place anyone would want to visit!
Much of this has to do with Venus' atmosphere, which is incredibly dense and entirely hostile to life as we know it. And because of its natural density and composition, the average surface temperature of Venus is hot enough to melt lead. All of this adds up to some pretty interesting weather patterns, which are also incredibly hostile!
Venus Atmosphere:
Although carbon dioxide is invisible, the clouds on Venus are made up of opaque clouds of sulfuric acid, so we can't see down to the surface using conventional methods. Everything we know about the surface of Venus has been gathered by spacecraft equipped with radar imaging instruments, which can peer through the dense clouds and reveal the surface below.
From the many flybys and atmospheric probes sent into its thick clouds, scientists have learned that Venus' atmosphere is incredibly dense. In fact, the mass of Venus atmosphere is 93 times that of Earth's, and the air pressure at the surface is estimated to be as high as 92 bar – i.e. 92 times that of Earth's at sea level.
