Scale of the Solar System

Mr. Wilson tells the class that scientists are going to send a rover from the Earth to Mars. Describe how far the rover would travel based on the class model.

• 0.5 AU which would be 1.25 yards

• 1 AU which would be 1.25 yards

• 0.5 AU which would be 1 yard

• 20 AU which would be 1 yard

Describe how the distances between the orbits of the inner planets compare to the distances between the orbits of the outer planets.

• The distances between orbits of the outer planets are much smaller.

• The distances between orbits of the outer planets are much larger.

• The distances between orbits of the inner planets are much larger.

• There is no difference between the distances of the orbits of the inner planets and the outer planets.

Why do scientists use scale to study the Solar System?

• The solar system is too large to study without using scale

• The solar system is too small to study without using scale

• Scientists don't need to use scale because we have satelites

• All of the above

If we created a model Earth with a diameter of 58cm what diameter would the SUN need to be in order to be scaled correctly?

A student made a model of how the planets orbit the sun. She used a tennis ball to represent the sun. She used ping-pong balls to represent each planet and painted each one a different color. Then, she placed all the ping-pong balls equal distances apart in a line extending out from the sun.

What are two limitations of the student's model? (Limitations are things about the model that limit its accuracy.)

• She used the same size balls to represent the planets.

• She made planets orbit the sun.

• The planets are not the correct distances from the sun.

• The solar system can't be modeled using actual objects.
