the latitude

Latitude is a coordinate that is used to fix positions on a sphere. The latitude of a place is the distance of that place from the equator of the coordinate system, measured in degrees along a meridian. Places at the equator have a latitude of 0; the north pole has a latitude of +90° (or 90° north latitude), and the south pole has latitude −90° (or 90° south latitude). In the sky, latitude is used in the ecliptic and galactic coordinate systems. The corresponding second coordinate is the longitude.
