| (documentation CirclesOfLatitude EnglishLanguage "A CirclesOfLatitude an abstract east–west small circle connecting all locations around Earth (ignoring elevation) at a given latitude coordinate line.Circles of latitude are often called parallels because they are parallel to each other; that is, planes that contain any of these circles never intersect each other. A location's position along a circle of latitude is given by its longitude.There are five major circles of latitude from north to south are: ArcticCircle, TropicOfCancer, Equator, TropicOfCapricorn AnarcticCircle. The position of the Equator is fixed (90 degrees from Earth's axis of rotation) but the latitudes of the other circles depend on the tilt of this axis relative to the plane of Earth's orbit, and so are not perfectly fixed.
