EQUINOCTIAL LINES Meaning and
Definition
-
Equinoctial lines, also known as celestial equator or equinoctal colure, are imaginary lines on the celestial sphere that are used to locate positions of celestial bodies in relation to the Earth's equator. The term "equinoctial" is derived from the Latin word "aequinoctialis," which means "equal nights" and refers to the two points on the celestial sphere where the Sun's path intersects with the celestial equator during the equinoxes.
The celestial equator is an imaginary projection of the Earth's equator onto the celestial sphere. It divides the celestial sphere into two hemispheres, the northern and southern hemispheres, just like the Earth's equator divides the Earth into the northern and southern hemispheres.
The equinoctial lines are the meridians or great circles on the celestial sphere that intersect the celestial equator at right angles. They pass through the celestial poles and are used as reference points for determining the right ascension and declination of celestial objects. Right ascension is the angular distance eastwards along the celestial equator from the vernal equinox, while declination is the angular distance north or south of the celestial equator.
These equinoctial lines have significant importance in astronomy and navigation, as they assist in mapping the positions of stars, planets, and other celestial objects in relation to the Earth's equator. They serve as a celestial coordinate system that enables astronomers to identify and locate celestial objects at specific positions on the celestial sphere.

Etymology of EQUINOCTIAL LINES
The word "equinoctial lines" is derived from the Latin word "aequinoctialis", which means "belonging to the equinox". It comes from the Latin roots "aequus", meaning "equal", and "nox", meaning "night". The term "equinoctial lines" refers to the imaginary lines on the Earth's surface that run parallel to the equator and mark the points of equal day and night during the equinoxes.
