How long does the precession of Earth take?

Answer 1

Benjamin Awad

Great Year = 258 centuries, nearly.

Earth precession refers to the Earth's axial precession..

The Earth.s Pole-Pole axis revolves about the normal to the ecliptic (

Earth's orbital plane ) as axis, over a cone of semi vertical angle of

about 23.4^o. This not-easily-noticeable motion is slow and the

period of one revolution is nearly 258 centuries, This is called

Earth's precession.

Effect:

In the Calendar, Summer Solstice would gradually recede to

Winter Solstice, after 129 centuries.

Every year, the right-overhead Sun at the same equinox/solstice,

wherever it occurs, is delayed by about

#(24xx3600)/25800=3.35#sec/yearsec/year
