  1. Our Solar System By Beth Bright & Sam Smart

  2. Our Solar System is made up of: Our Sun Eight Planets and their moons A dwarf planet An Asteroid Belt Comets

  3. Orbit An orbit is the path one object takes as it travels around another object (as it revolves around another object.)

  4. Why do planets stay in orbit? The Sun is so gigantic it has a gravitational pull that keeps all the planets in orbit around it. Gravity is the force objects exert on each other which pulls them together. The orbits keep the planets from being pulled into the sun.

  5. Planets in our Solar System Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune The dwarf planet - Pluto

  6. Mercury Size: 3,032 miles across Distance from Sun: 36 million miles Length of revolution around Sun: 88 Earth days long Atmosphere: helium and hydrogen Temperature: 870° F to –300 °F Surface: rocky crust that is covered with craters Interesting fact: Mercury is just a little larger than Earth's Moon.

  8. Saturn Size: 2nd largest - 74,900 miles across Distance from Sun: 888 million miles Length of revolution around Sun: 29.4 Earth years Atmosphere: hydrogen and helium Temperature: –300° F Surface: does not have solid surface Interesting fact: has a ring system made up of ice and rock particles, some as big as a minivan

  10. Life on Mercury or Saturn? • To live something needs • Oxygen • Water • Food Mercury does not have oxygen or water and the temperature is hot enough to burn something up or so cold it would freeze so life could not survive on Mercury. Saturn does not have oxygen or water and its temperature is so cold something would freeze so no one could live on Saturn.

  11. Asteroids Asteroids are chunks of metal and rocks like pebbles. Some asteroids are big.

  12. Comets Comets are made up of rocks, dust and frozen gases. Comets have a tail when they get close to the sun.
