Quick Summary

Celestial latitude is a measurement used in astronomy to pinpoint the position of celestial objects within the ecliptic system of celestial coordinates. This system is one of several used to map the sky, including the horizon, galactic, and equatorial systems. The ecliptic system measures positions relative to Earth's orbital plane. Celestial latitude is analogous to terrestrial latitude, which measures distance north or south of the Earth's equator.123

The ecliptic system
Celestial longitude and latitude are defined with respect to the ecliptic and ecliptic poles. Celestial longitude is measured eastward from the ascending intersection of the ecliptic with the equator, a position known as the “first point of Aries,” and the place of the Sun at the time of…
