|Diameter (width) at equator||7,521 miles (12,104 km)|
|Average distance from Sun||67.2 million miles (108.2 million km)|
|Time to orbit Sun||224.7 days|
|Time to spin around own axis||243 days|
|Mass||0.82 x Earth?s mass|
|Gravity||0.9 x Earth?s gravity|
|Average surface temperature||867F (464C)|
|Number of moons||0|
Thick clouds in Venus?s atmosphere stop us from seeing the surface. Radar probes, such as Magellan, can peer through the clouds, revealing a planet dotted with volcanoes and covered with rolling lava plains.
Temperatures on Venus soar to over 860F (460C), making it hotter than any other planet. Its carbon dioxide atmosphere, which is 100 times heavier than Earth?s, traps heat like a greenhouse.
