英语词汇“celestial latitude”的英英意思、用法、释义、翻译、读音、例句、短语、词组-英语词典

5. Astronomy. The angular distance of a heavenly body from the ecliptic: called spec. celestial latitude. (See also ascending n., geocentric adj. 1, heliocentric adj. 1, and heliographic adj. 1)The history of this sense appears to be as follows. Originally the word was applied, on the analogy of the geographical use (see 4) to denote the angular distance of a point in the celestial sphere from the equator, measured along a secondary to the latter. This, however, was not accurately distinguished by name from the distance of a point from the ecliptic, the terms ‘latitude’ and ‘declination’ being employed indiscriminately with reference to both these ways of indicating position. (Cf. quot. c1400.) In modern use, the terms have been differentiated, declination being appropriated to what was originally and with historical propriety called ‘latitude’, while latitude became the name for distance from the ecliptic.
