Unformatted text preview: difficult to see the stars close to the Moon, but you can certainly note the fact that each night it rises about 50 minutes than the previous night, so the Moon's position relative to the stars has changed. Figure 10. The Moon makes one complete orbit of the Earth in 27.3 days, but it will not be again Full until a total of 29.5 days has passed. One orbit of the Moon takes 27.3 Days. This would be the Moon's Sidereal Period since it is the time for the Moon to be back in the same location relative to the stars, and this is also the time for one orbit.
