Precession of the Earth
WebGreat Year. The tilt of the Earth's polar axis remains constant but describes a circular path in space during a period known as The Great Year. The term Great Year has more than one major meaning. It is defined by scientific astronomy as "The period of one complete cycle of the equinoxes around the ecliptic, or about 25,800 years". The precession of the equinoxes is caused by the gravitational forces of the Sun and the Moon, and to a lesser extent other bodies, on the Earth. It was first explained by Sir Isaac Newton. Axial precession is similar to the precession of a spinning top. In both cases, the applied force is due to gravity. For a spinning top, … See more In astronomy, axial precession is a gravity-induced, slow, and continuous change in the orientation of an astronomical body's rotational axis. In the absence of precession, the astronomical body's orbit would show See more Hellenistic world Hipparchus The discovery of precession usually is attributed to Hipparchus (190–120 BC) of Rhodes or Nicaea, a Greek astronomer. According to Ptolemy's Almagest, Hipparchus … See more A consequence of the precession is a changing pole star. Currently Polaris is extremely well suited to mark the position of the north celestial pole, as Polaris is a moderately bright … See more "Precession" and "procession" are both terms that relate to motion. "Precession" is derived from the Latin praecedere ("to precede, to come … See more The precession of the Earth's axis has a number of observable effects. First, the positions of the south and north celestial poles appear to move in circles against the space-fixed … See more Hipparchus gave an account of his discovery in On the Displacement of the Solsticial and Equinoctial Points (described in … See more The images at right attempt to explain the relation between the precession of the Earth's axis and the shift in the equinoxes.
