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.
