The "sun" is lighted with an ultra-bright 1000-hour light bulb inside a yellow orb to shine 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 a spectacular effect. Base features planetary longitude marks so the planets can be set up to their correct positions. Plus, the unique stardome (included) converts the unit into a planetarium. Powered by four C batteries (not included) or A/C adapter (not included in EI-5237).
