• Venus - Pictures and Astronomy Facts - Solar System Planetary Astronomical Data
  
  Venus, the second planet from the Sun, is often referred to as Earth's Sister. While similar in size to Earth, the atmosphere and living conditions on the planet are vastly different. With a very thick atmosphere, the pressure on the surface is nearly 90 times greater than on Earth. The thick atmosphere also makes the planet very hot (nearly 900 degrees).

  Scientists classify Uranus as a Jovian planet or gas giant. It has a rocky core, surrounded by a huge ocean of water mixed with rocky material. Its atmosphere is about 83% hydrogen, 15% helium and 2% methane. While most other plantes rotate on an axis which is nearly perpendicular to their orbit, Uranus's axis is closer to parallel. There is some debate as to which pole is north.
