1. The Eight Planets

   • Mad Vamipires Eat Mangoes And Jump Straight Up Noses.
   • A planet is something which orbits a Star
   • The Sun is our Star. There are eight planets that orbit our star
     • The Sun is really big meaning it has a big Mass. This also means its gravity is really strong.
       • The pull from the Sun's gravity keeps all of the planets in their orbit.
   • The Planets
     • Inner Planets
       • Mercury
       • Venus
       • Earth
       • Mars
       • All these Planets come before the Asteroid Belt and are closer to the Sun.
     • Outer Planets
       • Jupiter
       • Saturn
       • Uranus
       • Neptune
       • All these Planets come after the Asteroid Belt and are further away from the Sun then the Inner Planets.
   • Pluto is no longer a Planet. It is a Dwarf Planet.
   • The Planets all move in elliptical orbits (egg shaped circles)
   • Heat and Light
     • Planets DO NOT give off heat or light
     • Stars (like the Sun) DO give off heat and light

2. Information About The Planets

   • The Average Distance From Sun (in millions of km)
     • Mercury = 58
     • Venus = 108
     • Earth = 150
     • Mars = 228
     • Jupiter = 778
     • Saturn = 1430
     • Uranus = 2870
     • Neptune = 4500
   • Orbit Times
     • Mercury = 88 days
     • Venus = 225 days

3. Beyond The Solar System

   • Most of the Stars we see at night are in our own Galaxy
     • All the others are so far away that they look small and fuzzy.
   • The Universe is made up of MILLIONS of Galaxies.
     • The closest galaxy to us is Andromeda
   • At the end of our Solar System there is the 'Kuiper Belt'. Here is where the Dwarf Planet Pluto is.
     • Many other Dwarf Planets like Makemake and Eris are in this belt
