[[Image:Rotating Sphere.gif|right|thumb|A sphere rotating around an imaginary axis]] The '''axis of rotation''' is an imaginary line passing through the center of mass of any [[celestial body]] around which the [[celestia]]l body rotates. In case of [[Earth]], the axis of rotation of Earth passes through the [[north pole]], the centre of mass of Earth and the [[South Pole|south pole]]. The Earth makes one complete rotation around this imaginary axis every 23 hours, 56 minutes and four seconds. The line passes through the north and south poles of a [[planet]]. == Related pages == * [[Axial tilt]] * [[Rotation]] {{Sci-stub}} [[Category:Celestial mechanics]] [[Category:Geometry]]
