What is the root word of declination?
In astronomy, declination (abbreviated dec; symbol δ) is one of the two angles that locate a point on the celestial sphere in the equatorial coordinate system, the other being hour angle. The declination angle is measured north (positive) or south (negative) of the celestial equator, along the hour circle passing through the point in question.
DECLINATION definition: 1. an angle that gives the position of a point in space in relation to earth: 2. an angle that…. Learn more.
The meaning of DECLINATION is angular distance north or south from the celestial equator measured along a great circle passing through the celestial poles. How to use declination in a sentence.
What does declination mean? In astronomy, the declination of a celestial object (such as a star or planet) is its position in relation to the celestial equator —the imaginary flat surface that extends out from Earth’s equator in all directions.
In linguistics, declension (verb: to decline) is the changing of the form of a word, generally to express its syntactic function in the sentence, by way of some inflection.
the angular distance, esp in degrees, of a star, planet, etc, from the celestial equator measured north (positive) or south (negative) along the great circle passing through the celestial poles and the body. Symbol: δ. Compare: right ascension. 2. See magnetic declination. 3. a refusal, esp a courteous or formal one. Collins English Dictionary.
dec·li·na·tion. (dĕk′lə-nā′shən) The position of a celestial object above or below the celestial equator. It is measured as a vertical angle, from 0° at the celestial equator to 90° at one of the celestial poles. Declination and right ascension are the measurements used to map objects on the celestial sphere.
