Orion: One of the most recognisable constellations, Orion - "The Hunter" - can be seen throughout the world, and is one of the most prominent, located on the celestial equator
. Lepus: A constellation lying south of the celestial equator
and its more famous neighbour Orion, its name is Latin for "hare".
This fact gave a hint for a hypothesis that the histogram shape may depend not only on the proximity to the equinox moment, but also on the direction the Sun is moving to the celestial equator
: from the northern or from the southern hemisphere.
Since the spin axis of the Earth is inclined at 23.44[degrees] to the vertical of its orbital plane, the inclination of the ecliptic (path of Sun) is 23.44[degrees] to the celestial equator
(circle through the stars directly over the equator of the Earth).
The fall equinox begins autumn in the northern hemisphere-the moment when the sun appears to cross the celestial equator
and day and night are of approximately equal length.
Held between the historic axis of the Park and the N-S meridian line in plan, and clipped by the intersection between the axis of the North Star and the celestial equator
in elevation, the edges of the cone could not be anywhere else.
Located 21,000 light-years away, M13 in Hercules is the finest globular cluster north of the celestial equator
. The cluster resides on the west side of the Hercules Keystone, about two-thirds of the way from 2nd-magnitude Zeta ([xi]) Herculis to 3.5-magnitude Eta ([eta]) Herculis.
See if you can feel the exact moment when the sun pulls even with the celestial equator
, the imaginary line running from the equator into space.
In a fantasy photo-montage called Physics Illustrated, Caprice holds up the world for inspection, rides a crescent moon and sits astride the celestial equator
From the vantage point of the gate at sundown, the sun appears to descend into a narrow slot in the middle of the temple roof on the first day of fall and first day of spring - the two days the sun is directly on the celestial equator
. By running some calculations, he determined that the sun descends into the south corner of the temple roof on the first day of winter (when the sun is at its southernmost point) and into the north corner of the roof on the first day of summer (when the sun is at its northernmost point).
"We had been working some calibration stars near the celestial equator
, and I decided to swing the telescope to the zenith to obtain minimum background light and check performance in darker backgrounds.
declination The angular distance above (positive) or below (negative) the celestial equator
. One of the coordinates, with right ascension, that defines the position of a celestial object.
Philippine nights will be longer thereafter as the sun moves below the celestial equator
towards the southern hemisphere, PAGASA said.
