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).

But on Venus, the surface temperature is 460 degrees Celsius, day or night, at the poles or at the equator. Beyond its thick atmosphere, Venusâ axial tilt (aka. obliquity) plays a role in this temperature consistency.owever, for all the characteristics these two planets have in common, average temperature is not one of them. Whereas the Earth has an average surface temperature of 14 degrees Celsius, the average temperature of Venus is 460 degrees Celsius.
