![]() On a map, the circles of latitude may or may not be parallel, and their spacing may vary, depending on which projection is used to map the surface of the Earth onto a plane. Latitude can be in theory measured down to Planck length, and so there are vast number of circles of latitude on Earth. 34.637° N) or with minutes and seconds (e.g. There are 89 integral (whole degree) circles of latitude between the Equator and the poles in each hemisphere, but these can be divided into more precise measurements of latitude, and are often represented as a decimal degree (e.g. The Equator is the longest circle of latitude and is the only circle of latitude which also is a great circle. The Equator is at 0°, and the North Pole and South Pole are at 90° north and 90° south, respectively. ![]() The latitude of the circle is approximately the angle between the Equator and the circle, with the angle's vertex at Earth's centre. A circle of latitude is perpendicular to all meridians. The 60th parallel north or south is half as long as the Equator (disregarding Earth's minor flattening by 0.3%). Their length can be calculated by a common sine or cosine function. Circles of latitude are unlike circles of longitude, which are all great circles with the centre of Earth in the middle, as the circles of latitude get smaller as the distance from the Equator increases. ![]() ![]() A location's position along a circle of latitude is given by its longitude. This projection first came into use in the 16th century by the Dutch.Ī circle of latitude or line of latitude on Earth is an abstract east– west small circle connecting all locations around Earth (ignoring elevation) at a given latitude coordinate line.Ĭircles 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. The Mercator projection and its use on a world map. ![]()
