equinoxes's Usage Examples:

trepidare, to tremble), a term meaning, in general, fear or trembling, but used technically in astronomy for an imagined slow oscillation of the ecliptic, having a period of 7000 years, introduced by the Arabian astronomers to explain a supposed variation in the precession of the equinoxes.

In 1749 he furnished a method of applying his principles to the motion of any body of a given figure; and in 1754 he solved the problem of the precession of the equinoxes, determined its quantity and explained the phenomenon of the nutation of the earth's axis.

Each solstice is upon the ecliptic midway between the equinoxes, and therefore go from each.

Owing to the precession of the equinoxes it is longer than a tropical or sidereal year by 25 minutes and 2.

Violent winds are common at both equinoxes.

These seasons are governed by the apparent movements of the sun, the winters occurring at the equinoxes and the summers at the solstices.

in Europe the frequency near the equinoxes rises above that at midwinter, and we have a distinct double period, with a principal minimum at midsummer and a secondary minimum at midwinter.

The precession of the equinoxes is due to the fact that the earth performs a motion of this kind about its centre, and the whole class of such motions has therefore been termed precessional.

These are the equinoxes, solstices and cross-quarter days, progressing clockwise from the winter solstice at the top.

It also acted as an observatory, containing markers that enabled the Inca priests to predict eclipses, solstices and equinoxes (8 ).

The line of the equinoxes is the imaginary diameter of the celestial sphere which joins them.

These scholars also charted seasonal information regarding the equinoxes and solstices.
