celestial longitude
Astronomical coordinate systems are organized arrangements for specifying positions of satellites, planets, stars, galaxies, and other celestial objects relative to physical reference points available to a situated observer (e.g. the true horizon and north cardinal direction to an observer situated on the Earth's surface). Coordinate systems in astronomy can specify an object's position in three-dimensional space or plot merely its direction on a celestial sphere, if the object's distance is unknown or trivial. Spherical coordinates, projected on the celestial sphere, are analogous to the geographic coordinate system used on the surface of Earth. These differ in their choice of fundamental plane, which divides the celestial sphere into two equal hemispheres along a great circle. Rectangular coordinates, in appropriate units, have the same fundamental (x, y) plane and primary (x-axis) direction, such as a rotation axis. Each coordinate system is named after its choice of fundamental plane.

celestial longitude
Celestial longitude is a concept in astronomy that refers to one of the coordinates used in the equatorial coordinate system. It is expressed in degrees, and it measures the object's position eastward along the celestial equator from the vernal equinox. The celestial longitude of an object in the sky, together with its celestial latitude, allows its position to be precisely defined.
