Inner and Outer planets

Ethan, Maddie, and Justin

Warm Up

• In 3-5 sentences Define the inner and outer planets and what makes them different.

Objective

• Our objective is to know the difference between the inner and outer planets

Visual Aid

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

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

Distance

• The solar system is very big1. Mercury is 58 million km from the Sun 2. Venus is 108 million km from the Sun 3. Earth is 150 million km from Sun 4. Mars is 227 million km from Sun 5. Jupiter is 779 million km from Sun 6. Saturn is 1428 million km from Sun 7. Uranus is 2974 million km from Sun 8. Neptune is 4506 million km from Sun

• Notice how when we get to the gas giants that the distance between the previous planet gets bigger

Size Difference

• The sun is largest object in our solar system with a diameter of 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

Names

• Most of the planets in our solar system are named after roman gods1. Mercury after the messenger god2. Venus after the love/beauty god3. Mars after the war god4. Jupiter after the sky god5. Saturn after the god of agriculture6. Uranus named after the GREEK god of the sky7. Neptune after the god of the sea8. Pluto after the roman god of the underworld
