Orbit is inclined by about 7 degrees. Height of horizon line changes throughout the year. During the winter, the sun tracks lower in the sky (higher in summer) length of days. Most rise in the east and set in the west. For the most part, we see different stars at different times of the year (because of the earth revolving around the sun) As the earth revolves, the night sky faces different parts of the galaxy, depending on where the earth is in its orbit. Which stars you see also depends on your latitude. Instead of rising and setting, they trace a circular path around the north star.
