What is an inner planet • A planet whose orbit lies within the asteroid belt, i.e., Mercury, Venus, Earth, or Mars. • Also called terrestrial planets • The inner planets are composed mostly of rock • They are both smaller and denser than their counterparts. • They also have few or no moons and no rings circling them

  6. What is an outer planet • A planet whose orbit lies outside the asteroid belt, i.e., Jupiter, Saturn, Uranus, Neptune, or Pluto • Also called Jovian planets or gas giants • Are gaseous with no solid surfaces and only liquid cores • The outer planets are much larger than the inner planets • And all have rings

  8. Size Difference • The sun is largest object in our solar system with a diameterof 1377648 km • This means that the earth can fit into the sun over 1,000,000 times • Jupiter is the second largest object in our solar system with a diameter of 142740 km • The earth can fit into the Jupiter about 1,321.3 times
