b>ecliptic coordinate system is a celestial coordinate system commonly used for representing the positions and orbits of Solar System objects. Because most planets (except Mercury), and many small solar system bodies have orbits with small inclinations to the ecliptic, it is convenient to use it as the fundamental plane. The system's origin can be either the center of the Sun or the center of the Earth, its primary direction is towards the vernal equinox, and it has a right-handed convention. It may be implemented in spherical or rectangular coordinates.

Famous quotes containing the word system:
“Loving feels lonely in a violent world,
irrelevant to people burning like last year’s weed
with bellies distended, with fish throats agape
and flesh melting down to glue.
We can no longer shut out the screaming
That leaks through the ventilation system ...”
—Marge Piercy (b. 1936)
