There can only be one Cartesian North.
There is a general geographical difference, called magnetic declination. In addition, there may be differences that arise locally, as a result of nearby objects that attract a magnet, which is called magnetic deviation. Related links are given below.
The declination of the star Arcturus is 19 degrees, 11 minutes, while Polaris has a declination of 89 degrees 15 minutes. Their angular separation is the distance between them, approximately 71 degrees.
To determine the declination of a star, one can use a tool called a star chart or a star atlas. By locating the star in the night sky and referencing its position relative to the celestial equator, one can measure the angle of the star's position above or below the equator to find its declination.
Ah, the fall equinox is such a special time when the sun shines directly on the equator. Its declination is zero because it is right over that imaginary line. Nature is always keeping us in balance and harmony. Just visualize that warm sunlight hugging the Earth with love and peace. Stunning! Keep painting those happy little equations, my friend.
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.

True. Declination is the angular difference between true north (the direction of the North Pole) and magnetic north (the direction a compass points towards).

Declination on a map refers to the angular difference between true north (the North Pole) and magnetic north (the direction a compass needle points). This difference is important for accurate navigation with a compass, as it allows you to adjust your compass readings to align with the map.

Yes. "Declination" on the celestial coordinate system is the counterpart of "latitude" on the terrestrial coordinate system. Positive and negative declination correspond respectively to north and south latitude.
