The angle between the direction of star and the direction of earth’s axis of rotation is called A. Co-declination B. Co-latitude C. Declination D. Latitude

The correct answer is: C. Declination

Declination is the angle between the equatorial plane and the object’s apparent position in the sky. It is measured in degrees north or south of the celestial equator.

Co-latitude is the angle between the Earth’s axis of rotation and the observer’s zenith. It is equal to the latitude of the observer.

Co-declination is not a real term.

Latitude is the angle between the observer’s position and the Equator. It is measured in degrees north or south of the Equator.
