The International Date Line ( IDL) is the line between the South and North Poles that is the boundary between one calendar day and the next. It passes through the Pacific Ocean, roughly following the 180.0° line of longitude and deviating to pass around some territories and island groups. Crossing the date line eastbound decreases the date by ...
The Equator during the boreal winter, spanning from December to March. The equator is a circle of latitude that divides a spheroid, such as Earth, into the Northern and Southern hemispheres. On Earth, the Equator is an imaginary line located at 0 degrees latitude, about 40,075 km (24,901 mi) in circumference, halfway between the North and South ...
The first aerial circumnavigation of the world was completed in 1924 by four aviators from an eight-man team of the United States Army Air Service, the precursor of the United States Air Force. The 175-day journey from April to September covered over 26,345 miles (42,398 km). [ 1] The team generally traveled east to west, around the northern ...
String girdling Earth. String girdling Earth is a mathematical puzzle with a counterintuitive solution. In a version of this puzzle, string is tightly wrapped around the equator of a perfectly spherical Earth. If the string should be raised 1 metre (3 ft 3 in) off the ground, all the way along the equator, how much longer would the string be?
Geodesy. Earth's circumference is the distance around Earth. Measured around the equator, it is 40,075.017 km (24,901.461 mi). Measured passing through the poles, the circumference is 40,007.863 km (24,859.734 mi). [ 1] Measurement of Earth's circumference has been important to navigation since ancient times. The first known scientific ...
She would skim the equator, traveling 27,000 miles in the process. “I want to do it because I want to do it,” she told Putnam, whom she’d married in 1931. Her famous plane was a Lockheed ...
The Quitsato Sundial is a cultural-tourist place located at La Mitad Del Mundo, near to Cayambe, 47 km north of Quito, Ecuador. It was built in 2006 and inaugurated in 2007 as an independent, non-profit project in a 24,756 ft 2 (2,300 m 2) area. Its main goal is to share crucial aspects of the astronomical knowledge of the prehispanic cultures ...
