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).

This makes Venus's surface hotter than Mercury's, which has a minimum surface temperature of 53 K (â220 Â°C; â364 Â°F) and maximum surface temperature of 693 K (420 Â°C; 788 Â°F), even though Venus is nearly twice Mercury's distance from the Sun and thus receives only 25% of Mercury's solar irradiance.
