Meaning and Definition
The branch of astronomy dealing with the mathematical description of celestial positions and motions on the imaginary celestial sphere, using spherical geometry.
The foundational theoretical framework for mapping the sky, calculating celestial coordinates, and understanding the apparent daily and annual motions of stars and planets as seen from Earth, excluding their physical properties or distances.
