WebThe Chandler wobble or Chandler variation of latitude is a small deviation in the Earth's axis of rotation relative to the solid earth, which was discovered by and named after American astronomer Seth Carlo Chandler in 1891. It amounts to change of about 9 metres (30 ft) in the point at which the axis intersects the Earth's surface and has a period of … WebAxial precession is the movement of the rotational axis of an astronomical body, whereby the axis slowly traces out a cone.

"WebThe tilt is relatively constant, 23.5 degrees, but the precession, which in the case of Earth takes 26,000 years, means that the axial tit will point, in relation to farway stars, in different directions. However, Nutation creates a small but significant in the angle of tilt of the Earth towards the Sun. " - Earth precession definition

According to Ptolemy's Almagest, Hipparchus measured the longitude of Spica and other bright stars. Comparing his measurements with data from his predecessors, Timocharis (320–260 BC) and Aristillus (~280 BC), he concluded that Spica had moved 2° relative to the autumnal equinox. He also compared the lengths of the tropical year (the time it takes the Sun t…

WebTilt is the angle between the earth's rotation axis, and its orbital plane around the sun. Precession is the phenomenon whereby the direction of the tilt changes, which is why Polaris won't always be the pole star (until it comes round again). The amount of the tilt also varies, but only by a few degrees. Share Improve this answer Follow WebEarth's axial tilt actually oscillates between 22.1 and 24.5 degrees. The reason for this changing obliquity angle is that Earth's axis also wobbles around itself. This wobble motion is called axial precession, also known …
