-in ‘astronomy’ + ‘navigation’, the celestial sphere is an ‘abstract sphere’, with an arbitrarily large ‘radius’, that is ‘con-centric’ to ‘earth’-
.
(all objects in the observer’s sky can be conceived as projected upon the inner surface of the celestial sphere, as if it were the underside of a dome or a hemispherical screen)
.
(the ‘celestial sphere’ is a practical tool for spherical astronomy, allowing observers to plot positions of objects in the sky when their distances are unknown or trivial)
