Length: 40,076 km
Encyclopedic Data: The equator is an imaginary line, stretching around 40,000 kilometers, that divides the Earth into the Northern and Southern Hemispheres. One of its most famous landmarks is the “Middle of the World” monument in Mitad del Mundo, Ecuador.
Historical Fact: The line of the equator was first established by French scientists in the 18th century — but their calculations were off. The true equatorial line, determined later using GPS, lies 240 meters further north.
Unique Physical Phenomena:- Day and night are always equal — 12 hours each.
 - On the days of the spring and autumn equinox, objects cast no shadow at noon.
 - The Earth’s rotation speed at the equator exceeds the speed of sound, making it the ideal location for satellite launches.
 
Interesting Fact: A full circumnavigation of the globe strictly along the equator has never been achieved.
Exhibit Significance: The equator symbolizes both the boundary and the union of the two hemispheres of Earth, embodying the harmony of science and nature in creating extraordinary phenomena.
