Planetárium

Planetárium is a device used to simulate the sky and celestial phenomena. It typically consists of a dome-shaped projection screen and a central projector that displays stars, planets, and other astronomical objects. The projector can be manipulated to show the sky as seen from Earth at any given time, day, or location, as well as to simulate the movements of celestial bodies. This allows for educational demonstrations of constellations, planetary orbits, eclipses, and other astronomical events. Planetária are often found in science museums, educational institutions, and dedicated planetarium buildings. They serve as valuable tools for astronomy education, public outreach, and entertainment, offering immersive experiences of the cosmos. The technology behind planetária has evolved significantly, from early mechanical projectors to modern digital systems capable of highly realistic and interactive simulations.
