The Moon moves noticeably on the celestial sphere over the space of a single night. To show this, calculate how long it takes the Moon to move through an angle equal to its own angular diameter (1/2 degrees) against the background of stars. Give your answer in hours.
(b) Through what angle (in degrees) does the Moon move during a 12-hour night? Can you notice an angle of this size?
I guess what i really need to know is how to find the answers to these questions, not the actual answer because if I know how, I know I can do it on my own. Please help by telling me how to do this.
