Answer:
Since the North Star is directly in line with Earth's axis, all other stars appear to circle the North Star each night as Earth rotates. Because Earth is simultaneously revolving around the sun as it rotates on its axis, constellations in different parts of the sky are only visible during certain seasons.
Explanation:
First of all, some constellations are never visible from certain places on the Earth. For example, people in the Southern Hemisphere can't see the North Star (Polaris) because the Earth is always in the way. ... The Declination is very closely related to your latitude on the Earth.
