Quizplus · Accepted Answer

The declination of a star remains constant as it is a measure of its position in the sky relative to the celestial equator. However, the other options are all variables that change over the course of the night as stars appear to move across the sky. The star at your zenith will change as the Earth rotates, causing different stars to be visible at different times. The altitude and azimuth of a particular star will also change as it moves across the sky.
