Demonstrate the rotational motion of Earth on its axis, its orbit around the Sun, and the revolution of the moon around Earth with this high-quality model.

• Battery operated sun
• Moon rotates around the Earth
• Illustrates the different seasons

As the Sun casts a beam of light onto Earth (via an embedded LED), users can easily manipulate the positions of each body to examine how their dynamics correspond to seasons, eclipses, and lunar phases.
