ecliptic system

There are more coordinate systems besides the equatorial right ascension/declination system and the ecliptic system.

The ecliptic system of celestial longitude and celestial latitude specifies positions relative to the Earth's orbit.

The ecliptic system was the principal coordinate system for ancient astronomy and is still useful for computing the apparent motions of the Sun, Moon, and planets.

The ecliptic system describes the planets' orbital movement around the sun, and centers on the barycenter of the solar system (i.e. very close to the sun).

The underlying technology for the system, made by Ecliptic Systems of Palo Alto, Calif., has a lot to keep track of - 232 Godiva retail shops and 2,500 Godiva counters in department and specialty stores.
