Venus is the second closest planet to the sun. It is also the hottest planet.


Venus was discovered many years ago when ancient astronomers noticed that it moved in the night sky. It was named after the Roman goddess of beauty, Venus.

Predicted FutureEdit

Along with Earth and Mercury, in about 5 billion years, Venus is predicted to be destroyed when the Sun turns into a Red Giant.

  • Venus is the hottest planet due to the greenhouse effect. Venuses clouds trap in the sun's heat and releases a small amount, so it heats up, like a greenhouse.
  • Venus is a terrestrial planet, like Earth, Mars, and Mercury.
  • Venus is very close in size to the planet Earth.
  • It is the brightest object in the sky after the Sun and Moon.
  • Venus has phases just like Earth's Moon.
  • Its diameter is 12,104 km.
  • Venus has a blue sunset.
  • One year on Venus equals 1,92 days on Venus.
  • Without it's greenhouse effect, the average temperature on Venus would be only 254 degrees Kelvin (-19.15°C). If it had a greenhouse effect similiar to that on Earth (+35 °K), mean temperatures would be 289 °K or 15.85°C; meaning it could have sustained life.
