A celestial globe is a three-dimensional model of the celestial sphere, representing stars, constellations, and other celestial objects. It is typically mounted on a stand and can rotate to simulate the movement of the heavens as seen from Earth. The globe is often marked with lines of celestial latitude and longitude, helping users understand the positions of stars and planets. Historically, celestial globes were used by astronomers and navigators to study the night sky and assist in navigation. They are often made of materials like wood or metal and can be beautifully decorated. Celestial globes are related to other astronomical tools, such as the armillary sphere and astrolabe.
