This line is not arbitrary; it is the midpoint between the North and South Poles, making it the longest circle of latitude and the only one that is a great circle. While latitude relative to the North Star was relatively easy to measure in the Northern Hemisphere, finding the equator in the Southern Ocean required precise calculation.
Equator Weather at Zero Latitude: Understanding the Climate and Geography
Navigation and the Historical Context Historical Measurement and Exploration Historically, determining latitude was a critical challenge for sailors and explorers. Due to the direct angle of sunlight year-round, equatorial regions typically experience hot and humid weather with minimal seasonal temperature variation.
Early navigators used tools like the astrolabe and sextant to measure the angle of the sun or stars above the horizon to determine their position relative to this vital line, which was essential for long-distance sea travel and mapping the unknown world. However, the Equator does have a unique effect on physics; because it is the widest part of the Earth, the centrifugal force is slightly stronger there, making the effective gravitational pull slightly less than at the poles.

The Equator serves as the central horizontal axis for this system. It is an angular measurement, usually expressed in degrees and denoted by the Greek letter phi (φ).
