The celestial sphere is a theoretical sphere on which celestial objects appear to lie.

From the North Pole, one can see half of the celestial sphere throughout the year. This is because the Earth's axis of rotation is tilted, but over the course of a year, all the objects in one - half of the celestial sphere are visible.
