0 sources
The celestial sphere is a conceptual model used in astronomy to describe the apparent positions of celestial objects as seen from Earth [1]. It is imagined as a large sphere surrounding Earth, upon which all celestial bodies appear to be projected. This model provides a convenient framework for mapping the sky and describing the locations of stars, planets, and other astronomical objects relative to an observer. The concept helps astronomers and navigators describe directions in the sky using simple angular coordinates, regardless of the observer's actual location on Earth's surface.
