one of two points of intersection of the Earth's axis and the celestial sphere.
A great circle passing through the two poles of the celestial sphere and the zenith of a given observer.
The point on the celestial sphere toward which the sun and solar system appear to be moving relative to the fixed stars.
Latin: “Balance”), in astronomy, zodiacal constellation lying between Scorpius and Virgo, at about 15 hours 30 minutes right ascension (the coordinate on the celestial sphere analogous to longitude on the Earth) and 15° south declination (angular distance south of the celestial equator).
Either half of the celestial sphere as divided by the ecliptic, the celestial equator, or the horizon.
Nevertheless, the notion of the direction of rotation is fully applicable to the visible galaxies projected onto the celestial sphere.
A polar projection of half or more of the celestial sphere on a chart equipped with an adjustable overlay to show the stars visible at a particular time and place.
The position of two celestial bodies on the celestial sphere when they have the same celestial longitude.
(astronomy) the angular distance to a point on a celestial object measured north or south from the celestial equator; expressed in degrees; used with right ascension to specify positions on the celestial sphere.
Such music can be heard but in celestial spheres, how many times has it been played for human ears?
a great circle on the celestial sphere passing through the zenith and perpendicular to the horizon.
a point in the heavens (on the celestial sphere).
(astronomy) moving from east to west on the celestial sphere; or--for planets--around the sun in a direction opposite to that of the Earth.
If you have set your system clock to the correct time then the instruments will be shown in the correct relationship to the stars on the celestial sphere.
(astronomy) the angular distance eastward along the celestial equator from the vernal equinox to the intersection of the hour circle that passes through the body; expressed in hours and minutes and second; used with declination to specify positions on the celestial sphere.
A point on the celestial sphere directly below the observer, diametrically opposite the zenith.
The point on the celestial sphere that is directly above the observer.
