polar distance मीनिंग इन हिंदी

उदाहरण वाक्य

1. Hence ( the points ) where the ecliptic and the equator intersect should give the north polar distances of the spring and autumn equinoxes.
2. Towards the end of her life, she arranged two-and-a-half thousand nebulae and star clusters into zones of similar polar distances.
3. The advantage of a transit circle over a mural circle ( which can measure polar distances ) is that it allows measuring right ascension and declination at the same time.
4. This would have allowed them to measure the north polar distance ( declination ) a measurement that gave the position in a " xiu " ( right ascension ).
5. The difference between the circle reading after observing a star and the reading corresponding to the zenith was the zenith distance of the star, and this plus the colatitude was the north polar distance.
6. To determine absolute declinations or polar distances, it was necessary to determine the observatory's colatitude, or distance of the celestial pole from the zenith, by observing the upper and lower culmination of a number of circumpolar stars.
7. If the polar distance of the Sun is equal to the observer's latitude, the shadow path of a gnomon's tip on a sundial will be a parabola; at higher latitudes it will be an ellipse and lower, a hyperbola.
8. The mean position of the North Star Polaris ( Alpha Ursae Minoris ) on the first of January was Right Ascension, 1 hour, 41 minutes, 59 seconds; North Polar distance, 1 hour, 1 minute, and 33.8 seconds.
9. In the celestial equatorial coordinate system ? ( ?, ? ) in astronomy, "'polar distance "'( "'PD "') is an angular distance of a celestial object on its meridian measured from the celestial pole, similar to the way declination ( dec, ? ) is measured from the celestial equator.
10. Ptolemy's catalog in the " Almagest ", which is derived from Hipparchus's catalog, is given in equatorial coordinates : in his commentary on Eudoxos he provides stars'polar distance ( equivalent to the declination in the equatorial system ), right ascension ( equatorial ), longitude ( ecliptical ), polar longitude ( hybrid ), but not celestial latitude.
