How does the equatorial system divide the celestial sphere?
Using declination and right ascension
On the celestial sphere what is the North Stars declination?
The declination of Polaris (the north star) is: + 89° 19' 39'That's just 0.6725 degree from the north celestial pole.
What are the components of celestial sphere?
The components of the celestial sphere include the celestial equator (dividing the sky into northern and southern hemispheres), the north and south celestial poles (points around which the sky appears to rotate), and celestial coordinates (such as right ascension and declination) used to locate objects in the sky. Additionally, the ecliptic (the apparent path of the Sun) intersects the celestial equator at two points known as the vernal and autumnal equinoxes.
What is the difference in declination angles between the north and south celestial poles?
The Earth orbits on its axis. It isn't a physical axis; there is no metal rod through the Earth, but we can calculate it pretty well. If you were to extend that imaginary axis straight out from the physical poles, this would point to the "celestial poles". Early astronomers thought of the sky as a solid crystal sphere, and all the stars were at the same very great distance away. We know now that isn't true; all the stars are at their own distances, all different. But we still sometimes speak of the "celestial sphere", and the celestial poles, and the celestial equator. This helps us to visualize where we are in the galaxy, and where all the stars are in relationship to each other.
What is the celestial equivalent of latitude?
The declination of a celestial object is the exact equivalent of latitude.

Where in the celestial sphere is Capricorn located?
The coordinates of Capricornus in the celestial sphere are: Right Ascension 20h 06m 46.4871s - 21h 59m 04.8693s and Declination −8.4043999°- −27.6914144°.
What is the angular distance of aheavenly body from a fixed point?
If the fixed point is the intersection of the celestial equator and the hour circle that intersects the body's position on the celestial sphere, it is declination.
Where would the earth be located in a model of celestial sphere?
The celestial sphere has the Earth at the centre and all the objects in the sky situated on the sphere at infinite distance. Positions of the objects are described by two coordinates, which could be azimuth and elevation, or, in geocentric coordinates, declination and hour-angle.
What is the right ascension and declination of constellation Capricornus?
Right ascension: 21 h Declination: −20°
What is the star latitude and star declination?
Celestial coordinates. -- The star's latitude on the celestial sphere is the same as the Earth latitude that it seems to follow on its way aroujnd the sky. On the celestial sphere, the latitude is called "declination", and is expressed in degrees. -- The star's longitude on the celestial sphere is its angle, measured westward, from the point in the sky called the Vernal Equinox ... the point where the sun appears to cross the celestial equator in March. On the celestial sphere, the star's longitude is called "Right Ascension", and it's expressed in hours. That certainly seems confusing, but an "hour of Right Ascension" just means 15 degrees of celestial longitude. So, as the sky turns, the point directly over your head moves through the stars by 1 hour of Right Ascension every hour.
What are the components of celestial sphere?
The components of the celestial sphere include the celestial equator (dividing the sky into northern and southern hemispheres), the north and south celestial poles (points around which the sky appears to rotate), and celestial coordinates (such as right ascension and declination) used to locate objects in the sky. Additionally, the ecliptic (the apparent path of the Sun) intersects the celestial equator at two points known as the vernal and autumnal equinoxes.
What is the point on the celestial sphere located at o hours right ascensions and o degrees declination?
The point on the celestial sphere located at 0 hours right ascension and 0 degrees declination is known as the vernal equinox. It marks the point where the celestial equator intersects the ecliptic and is used as the reference point for defining celestial coordinates. It also marks the beginning of spring in the Northern Hemisphere.

Are the stars located with the respect to the celestial sphere on the surface of the sphere?
No, because there is no such thing as the celestial sphere. So there is no inner surface of a celestial sphere.
What is the celestial equivalent of latitude?
The declination of a celestial object is the exact equivalent of latitude.
