How long does the moon take to complete the two motions of rotating on its axis and revolving around the earth?

Answer 1

That would depend on the speed. The Moon is near the Earth, so you can take the Earth-Sun distance, which is 150 million kilometers. At the speed of light, it takes 8m 20s. At a slower speed, obviously it will take longer. Use the formula distance = speed x time. Solving for time: time = distance / speed. Be sure to use compatible units. For example, if the distance in kilometers, and the speed in kilometers / second, then the time will be in seconds.

Answer 2

One way of measuring how long it takes the Moon to orbit the Earth is by measuring how long it takes for the moon to appear. This is done by measuring the length of the moon's phases. This can also be measured by timing how long it takes a radar beam traveling at the speed of light.

Answer 3

First off, it's not the stars that are moving (at least not appreciably), it's the Moon.

The apparent motion of the Moon relative to the fixed stars is just about 33 minutes (of arc) per hour. The Moon's angular diameter from Earth is approximately the same.

Both of these vary depending on exactly where the Moon is in its orbit, and when the Moon is furthest away (and therefore the smallest) it's also moving the slowest, so the two factors roughly cancel out, and it's fairly reasonable to say that the moon moves by about its own diameter every hour (again, relative to the fixed stars... relative to the horizon, it moves about 30 times further than that, but so do the stars near the Moon's orbit).

Therefore, if the Moon occults a star (that is, the star disappears behind the Moon's disc from our point of view), that star will reappear on the other side about an hour later if it goes behind the widest part of the moon, or in somewhat less time if it passes north or south of that line. For reasons that should be obvious if you've been paying attention this far, reporting a value in seconds would imply a wholly unjustified degree of precision (for any specific occultation, it is possible to calculate its length down to the second, but it also involves considerably more computation than I personally feel like doing ... if you really care, you could look it up in what's called a table of ephemera).
