The brilliance of the night sky right in your living room. Each of the 88 constellations recognized by the International Astronomical Union is depicted using a series of star shapes, dots, and lines to give the impression of varied distances and sizes. Stars are shown in a metallic silver tone atop a deep black backdrop, allowing every shape to pop. Makes a great gift for astronomy lovers. Turns using ambient light; Hidden magnets provide movement; No cords, no batteries, no charging.
