Alpha Centauri appears as a bright object visible in the Milky Way galaxy. Alpha Centauri is actually a system of three objects. Each object produces light and rotates on its own axis. The system is an average of 4 light-years from Earth. Based on this information, the three objects that make up the Alpha Centauri system are all —

• asteroids

• comets

• planets

• stars

Which statement best describes the location of the sun in the Milky Way galaxy?

• The sun is located in the center of a spiral-shaped galaxy.

• The sun is located off the center of an elliptical-shaped galaxy.

• The sun is located on an arm of a spiral-shaped galaxy.

• The sun is located on an arm of an elliptical-shaped galaxy.

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
