Question

L. Instead of focusing on buildings or trees, we often use the zodiac constellations as our coordinate system i.e we use the stars as our frame ofreference. That is, all our observations and measurements are made from the perspective we would have if riding' a star. In this frame of reference, what is the average velocity ofa zodiac star? In this frame of reference, does the sun generally travel East to West or West to East? i. ii. iii. In this frame of reference, iv. Approximately how frequently do exceptions to either of the V. In this frame of reference, does the moon generally travel East to West or West to East? above (sun or moon changing direction) arise? do the sun and the moon travel at approximately the same velocity? vi. If so, approximately what is this velocity? vii. If not, which travels slower-and by approximately how much? M. In Earth's frame of reference (from our perspective), the sun travels through our sky and around us. From one sunrise to the next we say that a day of time has passed. How many days are there in a year? N. To what observable cycle of sky events does the term year apply? That is, what do we physically mean by a 'year? O. Let's remind ourselves:
