ecliptic coordinate system

Calculate the coordinates of the Sun in the ecliptic coordinate system.

See Ecliptic coordinate system for further information.

The midheaven (MC) is a point of definition in the ecliptic coordinate system.

Deep space satellites use other Celestial coordinate system, like the Ecliptic coordinate system.

The ecliptic is the apparent path of the Sun on the celestial sphere, and is the basis for the ecliptic coordinate system.

The ecliptic coordinate system is a celestial coordinate system commonly used for representing the positions and orbits of Solar System objects.

A position in the ecliptic coordinate system is thus typically specified true equinox and ecliptic of date, mean equinox and ecliptic of J2000.0, or similar.

He also produced tables dealing with transformations between coordinate systems on the celestial sphere, such as the transformation from the ecliptic coordinate system to the equatorial coordinate system.

Thus, the need to use stars close to the ecliptic ( 9 of latitude) as a set of observational reference points to help positioning a planet within this ecliptic coordinate system.

Because of the precession of the Earth's axis, the position of the vernal point on the celestial sphere changes over time, and the equatorial and the ecliptic coordinate systems change accordingly.

Although the zodiac remains the basis of the ecliptic coordinate system in use in astronomy besides the equatorial one, the term and the names of the twelve signs are today mostly associated with horoscopic astrology.

Modern astronomy still uses tropical coordinates for predicting the positions the Sun, Moon, and planets, except longitude in the ecliptic coordinate system is numbered from 0 to 360 , not 0 to 30 within each sign.

Beyond the celestial bodies, other astrological points that are dependent on geographical location and time (namely, the Ascendant, the Midheaven, the Vertex and the houses' cusps) are also referenced within this ecliptic coordinate system.

Essentially, the zodiac is a celestial coordinate system, or more specifically an ecliptic coordinate system, which takes the ecliptic as the origin of latitude, and the position of the sun at vernal equinox as the origin of longitude.
