Planets and the Sun How Do We Size Up? Seventh Grade Science Size • In order to determine size, we need a point of reference • A jet flying in the sky appears to be small due to distance, on the ground, it is very big • How does the Earth compare in size to the rest of the solar system? Our Solar System The Sun is a Star • The sun is an average sized star • Over one million Earths can fit into the sun • All the stars you see in the night sky are tiny because they are so far away • Most of the stars are larger than our sun!! Types of Stars • Stars come in different sizes • Lets take a journey to see how we compare to the rest of the objects in our solar system and our galaxy • https://www.youtube.com/watch?v=US_O0uK 5piA Early Astronomers • Looked into the night sky and charted what they saw • They only looked with the unaided eye • Examine the Power Point on Early Astronomers to find out about their theories of the solar system
