The equator is a circle of latitude that divides a spheroid, such as Earth, into the northern and southern hemispheres. On Earth, it is an imaginary line located at 0 degrees latitude, about 40,075 km (24,901 mi) in circumference, halfway between the North and South poles. The term can also be used for any other … See more The name is derived from medieval Latin word aequator, in the phrase circulus aequator diei et noctis, meaning 'circle equalizing day and night', from the Latin word aequare 'make equal'.

Measuring accuracy of latitude and longitude
WebThis improved coordinate system defines a celestial equator as a projection of Earth's equator in the sky. North and South celestial poles are +/- 90 degrees from the celestial equator. These are also projections of Earth's North and South poles into the sky. WebAngular distance is the measure of an arc (a segment of the circumference of a circle). Angular distance measures the proportion of a circle that the arc in question consists of. [>>>] Angular distance on the celestial sphere measured along the great circle from the zenith to the celestial object. Zenith distance is 90° minus altitude. [S92] Webmeasurement into decimal degrees. To convert 45° 33' 22", first multiply 33 minutes by 60, which equals 1,980 seconds. Next add 22 seconds to 1,980: 2,002 total seconds. Now compute the ratio: 2,002/3,600 = 0.55. Adding this to 45 degrees, the answer is 45.55°. bro is 7\\u002711
