Observe the vastness of space in a dramatic light show! The "sun" is lighted with an ultra-bright 1000-hour light bulb that shines onto the planets as they orbit around it. The central tower and the planetary support rods are black so that they "disappear" in a darkened room for spectacular effect! Plus, the unique star dome converts any room into a planetarium! Requires 4 "C" batteries, not included.
