Venus is often referred to as Earth's Twin. It has a similar size to Earth the way Mars is similar to earth, and is made of the same materials. It also has similar surface composition and an atmosphere with complex weather system like Earth does. Many Astrobiologists study Venus and its runaway greenhouse gas effect to gain insight as to the earths greenhouse gas issues.
Of course there are differences too. Venus's atmosphere is 96.5% CO2, but get this: The Earth has its CO2 stored on Calcite type rocks. If all of it were converted into atmospheric CO2, it would the same amount as in Venus's atmosphere today. Irrelevant? Maybe, but interesting nonetheless.
