Latitude. In astronomy an imaginary great circle is drawn through a star and the pole of the ecliptic. The distance along this circle between" the star and the ecliptic is its celestial latitude, and the distance along the ecliptic from the first point of Aries to the point where the same great circle cuts the ecliptic is its celestial longitude. These two measurements define the position of any celestial body.
