Venus is the hottest planet in the solar system, with an average surface temperature of 872 degrees Fahrenheit. The average temperature for the whole planet is 864 F. The reason for its high temperatures is not its proximity to the sun, but its heavy atmosphere composed mainly of carbon dioxide.
Temperatures on Venus are highly uniform, not only because of its dense atmosphere, but because of its minimum axis tilt of 3.36 degrees, as opposed to Earth's 23.4 degree tilt, which produces significant seasonal change in mean temperatures. Scientists believe that Venus' atmosphere was once like Earth's, but a runaway greenhouse effect made it the way it is today. This is why it receives a great deal of attention by those who study climate change.Learn More
Venus is one of the brightest objects in the night sky because the thick clouds that surround the surface reflect most of the light that reaches it. Another reason Venus appears so bright is due to the fact that it is the closest planet to the Earth.Full Answer >

The temperature on Venus remains constant at 461 degrees Celsius. The orbit of Venus around the sun is circular, which means that Venus does not experience seasons like other planets.Full Answer >
Venus is the third smallest planet in the solar system and is around 95 percent of the total size of the Earth. Both Earth and Venus are dwarfed by the largest planet in the solar system, Jupiter, which is more than 13 times their size.Full Answer >
