In astronomy, the ecliptic coordinate system is a celestial coordinate system commonly used for representing the apparent positions, orbits, and pole orientations[1] of Solar System objects. Because most planets (except Mercury) and many small Solar System bodies have orbits with only slight inclinations to the ecliptic, using it as the fundamental plane is convenient. The system's origin can be the center of either the Sun or Earth, its primary direction is towards the March equinox, and it has a right-hand convention. It may be implemented in spherical or rectangular coordinates.[2]
Ecliptic latitude; measured perpendicular to the ecliptic
A full globe is shown here, although high-latitude coordinates are seldom seen except for certain comets and asteroids.- ^ Cite error: The named reference
