The Equator is the line at 0° latitude crossing Ecuador, Kenya, and Indonesia.
The Equator is an imaginary circle around Earth, equally distant from the North and South Poles. It divides the planet into the Northern Hemisphere and Southern Hemisphere and serves as the reference from which latitude is measured. Its length is approximately 40,075 kilometres, varying slightly with Earth’s shape.
The line passes through South America, Africa, and maritime Southeast Asia. Countries crossed by it include Ecuador, Colombia, Brazil, São Tomé and Príncipe, Gabon, the Republic of the Congo, the Democratic Republic of the Congo, Uganda, Kenya, Somalia, Indonesia, and Kiribati.
The Equator does not guarantee identical daylight or temperatures everywhere along its route. Elevation, ocean currents, clouds, and local geography strongly affect climate. It also is not the same as the Prime Meridian, which runs at 0° longitude through locations including Greenwich, England.
