The average temperature on Venus is about 464 °C (867°F).
It is this hot because it is the second planet from the sun, and has what scientists call a 'runaway greenhouse' effect. A thick layer of clouds (carbon dioxide and some sulfuric acid) covers the surface and traps infrared radiation, raising the surface temperature of the planet.
The movement of the atmosphere gives the entire planet a nearly
uniform temperature all year long, even at the poles and even at
night. 900 degrees Fahrenheit The temperature at the surface of
Venus is 740 K (467 °C, 872 °F). 750 to 930 degrees Fahrenheit (398
to 498 Celsius).
The temperature doesn't vary much on the planet.The averagevalue is about 460 degrees Celsius.
