It is also the brightest star north of the celestial equator, just shading out Vega and Capella.
The Southern Sky or Southern Hemisphere is therefore thathalf of the celestial sphere that is south of the celestial equator.
For example, the Sun is north of the celestial equator for about 185 days of each year, south of it for about 180 days;
Barnard's Star is among the most studied red dwarfs because of its proximity andfavorable location for observation near the celestial equator.
The ecliptic and celestial equator intersect at two of these points: the Vernal(Spring) Equinox and Autumnal(Fall) Equinox.
The location isdefined by a pair of angular coordinates relative to the celestial equator: right ascension(α) and declination(δ).
Declinations south of the celestial equator are negative,declinations north of the celestial equator are positive.
Consequently, it contains also the north and south points on the horizon,and it is perpendicular to the celestial equator and horizon.
That point marks the intersection of your horizon with the celestial equator- the imaginary line above the true equator of the Earth.
The sun is on the celestial equator, and the celestial equator intersects all of our horizons at points due east and due west.
And, we see right here the prime celestial meridian, which as promised,meets the celestial equator in the constellation Pisces over here.
So here we have the celestial equator and if we raise our gaze a bit, then we can take a look at the celestial north pole here.
For the purpose of celestial mapping, the sky is considered byastronomers as the inside of a sphere divided in two halves by the celestial equator.
The term meridian comes from the Latinmeridies, which means both"midday" and"south", as the celestial equator appears to tilt southward from the Northern Hemisphere.
The southern celestial hemisphere, also called the Southern Sky, is the southern half of the celestial sphere; that is,it lies south of the celestial equator.
And so, we naturally have, splitting the distance between th'em, a celestial equator which is either the set of all points that are 90 degrees away from either of the poles.
The northern celestial hemisphere, also called the Northern Sky, is the northern half of the celestial sphere; that is,it lies north of the celestial equator.
The moment the Sun crosses the celestial equator and equalises night and day is calculated exactly every year and Iranian families gather together to observe the rituals.
This pertains not only to the very sophisticated astronomical methods that were used-who in ancient Sumer really needed to establish a celestial equator, for example?
NGC 2346(also known as the Butterfly Nebula)is a planetary nebula near the celestial equator in the constellation Monoceros.[1] It is bright and conspicuous and has been extensively studied.
The name Rucbah had also been applied to this star; though it shared that name with Delta Cassiopeiae.[11] It is only one of two stars withancient proper names to lie within a degree of the celestial equator.
Located less than five degrees south of the celestial equator in the eastern part of the constellation,[3] it forms a naked eye optical double with Delta Ophiuchi(named Yed Prior[11]).
It is about 20 seconds longer near a solstice when theprojection of the Sun's apparent motion along the ecliptic onto the celestial equator causes the Sun to move through a greater angle than usual.
As viewed from the North Pole,all fully visible constellations north of the celestial equator are circumpolar, and likewise for constellations south of the celestial equator as viewed from the South Pole.
In Western astrology, astrological signs are the twelve 30° sectors of the ecliptic,starting at the vernal equinox(one of the intersections of the ecliptic with the celestial equator), also known as the First Point of Aries.
In astronomy, hour angle is defined as the angulardistance on the celestial sphere measured westward along the celestial equator from the meridian to the hour circle passing through a point.[1] It may be given in degrees, time, or rotations depending on the application.
This in turn is determined by the positions of the Moon and Earth in their respective orbits,the inclinations of these orbits relative to one another and to Earth's celestial equator, and the observer's latitude on Earth.
So this is the zero right ascension circle.it is chosen so that it intersects the celestial equator and then some particular star, in this case, this star is in the constellation Pisces.
In astronomy, hour angle is defined as the angulardistance on the celestial sphere measured westward along the celestial equator from the meridian to the hour circle passing through a point.
Astronomical latitude is not to be confused with declination,the coordinate astronomers use to describe the locations of stars north/south of the celestial equator(see equatorial coordinates), nor with ecliptic latitude, the coordinate that astronomers use to describe the locations of stars north/south of the ecliptic(see ecliptic coordinates).
