That is actually a REALLY good question with an interesting answer! 😁 The Moon actually orbits the other way, west to east. So to answer your question, yes, the Moon rises in east and sets in the west due to the Earth's rotation, yes that's true. BUT! If the Earth stopped rotating, the Moon would go the other way about a half a degree per hour. It would rise in the west, stay in the sky for about *two weeks,* and then set in the east. Isn't that weird? Everything in the sky *appears* to go around the Earth at about 15 degrees per hour, or roughly once a day, due to Earth's rotation. So the Sun, the stars, the planets, and the Moon appear to go around about fifteen degrees per hour. But it reality, NOTHING does it right. The Moon "backs up" a half degree per hour, making it's total hourly progress about 14 and a half degrees. The stars move roughly an extra degree each day due to the Earth's orbit around the Sun. The Sun appears to speed up and slow down because of the eccentricity of Earth's orbit, so it rises and sets a few seconds earlier and later each day, speeding up and slowing down throughout the year, changing the overall length of the day/night cycle. And of course, the Moon and the planets all orbit around something else as we discussed, so they also appear to move among the stars at different rates. And of course, the stars themselves have their own proper motion too, so over the course of millennia they will move around compared to each other as well! EVERYTHING in the sky MOVES!!! 😁 So even though the Earth turns once per day, *nothing* in the sky moves exactly on that schedule. Everything in the sky also moves AROUND the sky too, at various rates, in various directions, and for various reasons. The sky only *appears* to be fixed and turning exactly once per day. |
