Celestial latitude is measured in degrees along a great circle drawn through the object being measured and the poles of the ecliptic, with positive values north of the ecliptic and negative values south of it, so that the ecliptic itself is 0° and the north and south ecliptic poles are +90° and −90° respectively.
