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 is the celestial equivalent of latitude?
The declination of a celestial object is the exact equivalent of latitude.
Where on the Celestial Sphere are the plants?
No plants have ever been observed on the Celestial Sphere.
What is celestial hemisphere?
It half of the celestial sphere, which is an imaginary sphere with the Earth at the centre, on which all objects in the sky can have their positions described by a type of latitude (declination) and a type of longitude (right-ascension). Declination goes from -90 degrees (south) to +90 degrees (north), while right ascension goes from 0 to 24 hours. They are called geocentric coordinates, and although we know the Earth is not at the centre of anything, they are useful in describing where to look for a star or to point a telescope.

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 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.
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.
Why do astronomers use Declination and Right Ascension?
These are coordinates that define the position of an object in the sky (on the "celestial sphere"). They are used in a similar way to how latitude and longitude are used, on the Earth's surface.
Is the imaginary sphere on which all objects in the sky seem to be located called the celestial sphere?
celestial sphere A+
Where on the Celestial Sphere are the plants?
No plants have ever been observed on the Celestial Sphere.
The imaginary sphere on which all objects in the sky seem to be located is called the celestial sphere.?
celestial sphere A+
