Introducing the Smithsonian Planetarium Projector by New York City-based NSI International Inc. Bring the nighttime sky into your room with this mesmerizing, dual-function planetarium projector. Just aim the projector at a light-colored wall or ceiling, and project a rotating star pattern of the northern sky. Three disks also feature 24 high-definition space images that you can project alongside the stars: planets, nebulae, moons, asteroids and other celestial bodies, as well as a satellite, space station, astronaut, space shuttle and more. Project more than 50 different image combinations. The Smithsonian Planetarium Projector features a 15-minute auto-shut-off, so you can fall asleep under a magical night sky. It comes with STEM educational content and requires 3 AA batteries (not included).
