Through parallax
The only star that does not appear to move in the Sky is Polaris, the North Star. (Actually it does move in a TINY circle, but the apparent motion is too small to notice.)
Why do searts appear to move westward across the sky?
A star turns in its own axis, causing it to rotate and appear to move across the sky. This rotation is what gives us the sense of day and night.
YES!!! Because '- #1 the Earth is rotating so it appears that the stars move across the sky. #2 the Stars in their own right also move. Since most stars are so far away their movement is hard to detect. #3 the Planets, appear to be stars, because they are pin point spots of light. The planets move , notably Venus, which can be seen as the Morning Star, or at a different time of the year as the Evening Star. The word 'planet' comes from Classical Greece, and means 'Wandering Star'.
The North Star, also known as Polaris, appears not to move in the night sky because it is located very close to the Earth's axis of rotation. This alignment makes it seem as though Polaris remains fixed while the other stars appear to rotate around it as the Earth spins on its axis.
To locate the North Star in the night sky, find the Big Dipper constellation and follow the two outer stars in its bowl to the North Star, which is the brightest star in the Little Dipper constellation. The North Star is always in the northern sky and remains stationary while other stars appear to move throughout the night.
They move accross the sky during the night due to our planets rotation. They also appear at different points in the night sky throughout the year due to our orbit around the sun and our relative position with the sun. This is where star signs come into it, your star sign is the costellation that the sun was in front of when you were born (but in reality this has shifted a bit so is not really the same as the dates you see quoted in the astrology column).
Stars appear to move in the sky due to the rotation of Earth on its axis. As Earth spins, it causes the stars to appear as if they are moving across the sky. This is known as the apparent motion of the stars.

Regulus stars appear to move across the sky from East to West (:
Polaris, also called the North Star, is just about in line with the north pole and so does not appear to move across the sky as other stars do.
The star that does not seem to move at night is called a "fixed star." This term refers to stars that, when viewed from Earth's perspective, appear stationary in the night sky because their motion is not easily observable within a single human lifetime.
