Celestial Sphere

In astronomy and navigation, the celestial sphere is a conceptual tool used in spherical astronomy to specify the position of an object in the sky without consideration of its linear distance from the observer. All objects in the sky can be conceived as being projected upon the inner surface of the celestial sphere. (Source: Wikipedia, the free encyclopedia)
