Bring the magic of space home with the GeoSafari Motorized Solar System! Eight colorful planets rotate around a glowing sun, just like they do in space! Remove the star dome cover to project the constellations on the wall or ceiling. Requires 4 AA batteries (not included). Encourage your little astronomer to explore the solar system with this motorized model that includes the sun, 8 planets, and the earth's moon. Inner and outer planets move at 2 different speeds to more realistically replicate the planets' movement around the sun
