What is NOT so great about Rice University? Unlike some other specific college threads where there are questions from people trying to decide whether or not they want to go there, here it is (obviously?) a foredrawn conclusion that Rice is the be-all, end-all.
Atmosphere: The surface temperature of Venus is around 890 degrees F, the hottest average temperature in the Solar System. This is due to a runaway greenhouse effect. The atmosphere of Venus is composed of 97% CO2, 2% N2 and less than 1% of O2, H2O and CH4 (methane).Since CO2 is a major greenhouse gas, the radiation from the Sun is trapped in the atmosphere of Venus producing an extremely high surface temperature.he atmosphere of Venus is composed of 97% CO2, 2% N2 and less than 1% of O2, H2O and CH4 (methane).

With no atmosphere, Venus would have a surface temperature of 130oC. With global clouds (which are present) but no greenhouse effect, Venus would have a surface temperature of minus 50oC. With global clouds and the actual greenhouse effect, Venus's real surface temperature averages at 470oC.
