• Pluto is 30% smaller than the Earth’s moon.So is called a dwarf planet.
  • It orbits around the kuiper belt where the comets are.

  • Saturn is also a gas giant mostly Hydrogen and Helium.
  • The fast winds in the upper atmosphere combined with the rising heat causes the planets Yellowish gold banding.
  • It is one of the windiest plant.
  • The distance from the sun 885,904,700 miles (1,426,725,400 kilometers).

  • Also known as the Jovian Giant.
  • It is the largest planet in our solar system.
  • The atmosphere is mainly Hydrogen and Helium which sort of resembles the sun.

Asteroids and Comets


  • Asteroids are rocky remains from the formation of the solar system about 4.6 billion years ago.
  • There are millions of asteroids in the belt.
  • The asteroid belt is between Mars and Jupiter.
  • The size of the belt is estimated about a few hundred feet and a few hundred miles in diameter.
  • There about four different types of asteroids so far known:
  1. Ceres these are the largest that they were classified as dwarf planets.
  2. Gaspra are made up of rocky and metallic minerals.The surface is covered with impact craters which is estimated 200 million years ago.
  3. Vesta are the third largest it has a very complex surface.
  4. Eros is the only asteroid with a very odd shape and it is also found out side the main a asteroid belt.


  • Comets are clumps of rocks and cold dirty ice.
  • They orbit very close to the sun but some of them go past Neptune called the Kuiper belt.
  • As the comet goes past the sun it melts a away a bit so a mixture of dust and gas is pushed from the comet by the solar wind.
  • The long tail is called a coma.
  • The tail always points away from the sun.

Planet Mars


  • Also known as the red planet.
  • This is a small rocky planet with volcanoes, meteor impacts, shifting of the tectonic plates and gigantic dust storms.
  • Distance from the sun 141,633,260 miles (227,936,640 kilometers).
  • Length of a year 687 days.
  • Length of a day 24 hours 37 minutes.
  • Minimum temperature -125 degrees Fahrenheit (-87 degrees Celsius).
  • Maximum temperature 23 degrees Fahrenheit (-5 degrees Celsius).

Planet Earth-Facts


  • This is our home planet and the only planet which inhabits life.
