Why is the moon sometimes visible during the day?

On some days, the moon is rather close to the sun, and it forms a very thin crescent. Since it's so close to the sun on those days, it rises and sets close to the same times when the sun rises and sets. This means it's in the sky pretty much all day, and NOT in the sky pretty much all night. Since it's close to the sun and it's just a thin crescent, it may be hard to spot during the day. You may be able to catch it in the west just after sunset, or (if you're an early riser) in the east just before sunrise. On other days, the moon is rather far from the sun, and may be on the complete opposite side of the sky. On those days, the moon appears full or nearly full on account of its position relative to the earth and to its light source (the sun). Since it's on the opposite side of the sky at those times, the moon rises in the east at more or less the same time that the sun is setting in the west. It will stay up more or less all night, and finally will set in the west at more or less the same time that the sun rises in the east. You'll also notice that the sun makes its way eastward over the course of a month. Try going out every night at the same time--say 7:00 PM, and notice whether you can see the moon, and where it is in the sky. If you catch it near the beginning of the lunar cycle, you'll see that it's in the west as a crescent (crescent always means it's fairly close to the sun). The next night at 7:00 you'll see that it's farther east; the next night still farther east; and so on. Eventually it's moved so far east that it will be near the eastern horizon at 7:00; and after that it will be below the horizon at 7:00. From that point you'll have to wait another couple of weeks before you can see it in the west (at 7:00) again. http://answers.yahoo.com/question/index?qid=20080113091006AAwDl6P Sep 01 10, 3:15 PM
