Earth's precession was historically called the precession of the equinoxes, because the equinoxes moved westward along the ecliptic relative to the fixed...

steady change in the orientation of the axis of rotation of the Earth, known as the precession of the equinoxes. Torque-free precession implies that no...

almanacs. Precession of the equinox was first noted by Hipparchus in 129 BC, when noting the location of Spica with respect to the equinox and comparing...

to the precession of the equinoxes, the time of year that the Sun is in a given constellation has changed since Babylonian times, and the point of March...

and Kochab. The precession of the equinoxes takes about 25,770 years to complete a cycle. Polaris' mean position (taking account of precession and proper...

The September equinox (or southward equinox) is the moment when the Sun appears to cross the celestial equator, heading southward. Because of differences...

respect to the fixed stars, resulting in a duration of 20 minutes longer than the tropical year, because of the precession of the equinoxes. Since antiquity...

point of Aries and first point of Libra: names referring to the astrological signs the Sun is entering. However, the precession of the equinoxes has shifted...

crosses the ecliptic, the other being the first point of Libra, located exactly 180° from it. Due to precession of the equinoxes since the positions were originally...

The point where the Sun crosses the celestial equator northwards is called the First Point of Aries. However, due to the precession of the equinoxes,...

referred to as precession of the equinoxes; secondly, that, due to the nature of the precession of the equinoxes, the progression of the ages proceeds...

to within 0.34% of current measurements). The precession of the solar apsides (as a motion distinct from the precession of the equinoxes), was first quantified...

navigation. The first seismic instrument was built in 132 AD. Isaac Newton applied his theory of mechanics to the tides and the precession of the equinox; and...

when the constellation of Aries or Ram appeared. This phenomenon occurred on the vernal equinox on March 21, but because of the precession of the equinoxes...

24219*86400/25772). Before the discovery of the precession of the equinoxes by Hipparchus in the Hellenistic period, the difference between sidereal...

because the coordinate systems of that type are themselves in motion, e.g. by the precession of the equinoxes, nowadays often resolved into precessional components...

for the precession of the equinox. Research into this theory is being conducted by the Binary Research Institute, which produced a documentary on the topic...

Astronomical precession Axial precession or precession of the equinoxes, the precession of the Earth's axis of rotation Apsidal precession, the rotation of the orbit...

Lunar precession is a term used for three different precession motions related to the Moon. First, it can refer to change in orientation of the lunar...

with the 24th century in second place with 12 claimants. Astrological ages are taken to be associated with the precession of the equinoxes. The slow wobble...
