I read an article that since the Moon must move Eastward among the constellations enough to go completely around the sky (360 degrees) in 27.3 days, it must move Eastward by 13.2 degrees each day . Thus, with respect to the background constellations the Moon will be about 13.2 degrees further East each day. Since the celestial sphere appears to turn 1 degree about every 4 minutes, the Moon crosses our celestial meridian about 13.2 x 4 = 52.8 minutes later each day.The cycle can therefore be expressed through the 28 days or separate phases of the Moon (though the natural cycle takes some 29½ solar days
BUT IF WE MULTIPLY 13 BY 28 = 364
I don't get these at all, can someone tell me what formula to use and how to solve these 2 problems step by step? Thank you!
