A student makes a model of the sun-Earth system by swinging a ball around her head. Using this model, the student is trying to explain how Earth stays on a path around the sun. The student explains that this path is the result of —

• the magnetic attraction between Earth and the sun

• potential energy stored in Earth that originated in the sun

• the gravitational attraction between the sun and Earth

• electromagnetic energy from the sun pulling on Earth

The Sun is the center of our solar system and creates a large amount of gravitational force. If this system lost the Sun, what would happen to the planets?

• The planets would explode.

• The planets would stop moving.

• The planets would travel in a different path.

Many objects within our solar system remain in constant motion and maintain predictable orbital patterns. What force governs the motion and patterns of objects in our solar system?

• The force of gravity keeps the Sun, asteroids, and comets orbiting in an elliptical pattern around the Earth.

• The force of gravity keeps planets, asteroids, and comets orbiting in an elliptical pattern around the Sun.

• The equal and opposite force between the Sun and the Earth keeps the comets and asteroids orbiting in an elliptical pattern.

• The Sun moves in an elliptical pattern and the planets, comets, and asteroids follow the gravity of the Sun in an elliptical pattern.
