The stars are always in the same position relative to the CENTER of the Earth. At least, you aren't going to notice the very small movement that they have - - it takes 1300 years for a star like Sirius to move 0.5 degrees.
But .. the stars do appear to move relative to your HORIZON. They circle around a point in the sky called the North Celestial Pole, taking close to full day to make one circle. So by noticing where the center of the star circle is, you can figure out which direction is north. When you look at this video, the center of the circle is not in the picture, but you could still figure out where it is. |
