ASTR 110 Group Project #1: Chap. 1 Conceptual Questions • (2 pts) Why is it more difficult to notice the westward motions of stars that are high in the sky than those that are near the horizon? • (2 pts) What is the latitude of the North Pole on Earth? Why is it impossible to give the longitude of the North Pole? • (2 pts) What range of azimuth would include all the locations on the horizon at which stars can rise? Would this question make sense to an observer at the North Pole? Explain. The motions are more easily seen when there is a fixed object (or reference point) for comparison. 90° N. All of the lines of constant longitude cross at the pole. 0° to 180°. No, because none of the observable stars in the sky rise or set at the North Pole.
