Semester Review: Astronomy

Why is making a model of the solar system difficult?

• Don't have the right materials

• The solar system is so big and the objects in it are so small in comparison

• There are too many parts in a model

• Because the science concepts are too difficult

Why is Pluto not a planet?

• It is not in orbit around the sun and acts more like a comet than a planet.

• It doesn't have a nearly-spherical shape.

• It has not cleared the neighborhood around its orbit of smaller objects. Gravity not strong enough to accomplish this task.

• It doesn't have any moons which is needed to be considered a planet.

For many centuries, most people believed all celestial objects such as stars and the sun revolved around Earth. But we NOW know this is wrong, NOT TRUE. The theory that is TRUE today is called what?

• Geocentric Theory

• Heliocentric Theory

• Center Theory

• Celestial Theory
