http://qrpdxpropagationantennas.com/terrestrial-directions-the-north 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

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.
