Why does the moon rise later every night?

Question

thanks

Answer 1

The first two people don't know what they are talking about, or they didn't pay attention to your question. The third person's answer is too complicated.

The moon slowly orbits around the Earth. As the moon orbits, it gradually moves from the dark side (night side) of the Earth to the day side of the Earth. This is why the moon seems to rise later each night. Eventually it will rise during the morning. Then it will seem to rise during the day, as the moon moves from one side of the Earth to the other as it orbits the Earth.

Answer 2

The Sun, Moon, and planets move along the sky with the planets, but also move relative to the stars. The motion between the stars (13 degrees per day for the Moon, about 1 degree or less for the Sun and the planets) is much slower than the rotation of the starry sky (360 degrees per day), so the motion relative to the stars doesn't stand out at first sight. So, the stars, planets, Moon, and Sun move through the sky in just about the same way.

The Sun, Moon, and planets cannot appear everywhere in the sky. As a rule of thumb, if you never see the Sun in a particular direction in the sky (for example, straight up or due north, if you are in Europe) then the Moon and planets cannot be in that direction, either.

The paths that the Sun takes through the sky throughout the year are all parallel to one another. On a summer's day, the Sun travels along a higher path (a "summer's path") and on a winter's day, the Sun takes a lower path (a "winter's path"). After the longest day, the Sun takes a lower path each day, until the shortest day, after which it takes a higher path each day, until the longest day comes around again.

The Moon and the planets travel roughly the same paths as the Sun, but not all the same path at the same time. The Sun is always highest in the sky at noon, but for the Moon or the planets this can happen at any time of day or night. It may happen that on a certain day Mars takes the path through the sky that the Sun takes on 6 November, and that Jupiter on that same day takes the path that the Sun takes on 22 April, and that Mars is highest in the sky around midnight and Jupiter about a quarter of an hour before the Sun.

Everything that rises (Sun, Moon, planets, and many stars) rises in the eastern half of the horizon and sets in the western half. The motion in the western half of the sky is the mirror image of the motion in the eastern half of the sky. Something that rises due east and is highest in the sky exactly 6 hours later sets exactly another 6 hours later due west (except for minor differences especially for the Moon because of its motion relative to the stars).

The phase of the Moon (Full Moon, Last Quarter, New Moon, First Quarter) changes so little in one night that you can pretend that the phase is the same all night long. If the Moon rises as a thin crescent, then it will set as a thin crescent, too.

Answer 3

heh wow...

Ok the second answer is actually very good despite what the guy above me said.

The moon orbits the Earth once every 27.3 days or so. That means that each day it is at a different point in the sky relative to the fixed stars. The sun also moves relative to the fixed stars because the Earth is orbiting it, but it's motion through the sphere is much slower, it takes a year to go around. Since the moon moves faster through the celestial sphere (in an easterly direction) than the sun, it will rise and set anywhere between 30 mins to over an hour later each day.

Answer 4

The Earth's rotation makes the Moon appear to be travelling from the eastern horizon to the western horizon. At the same time, however, the Moon's motion in its own orbit is moving it back towards the eastern horizon. If you observe the Moon at moonrise and note its position among the stars, you will find that at moonset it is in a different position. Stars that rise with the Moon set a little before it. By the time the next moonrise comes along the Moon has moved further in its orbit and hence rises later than it did the first night.

Answer 5

The Earth is spinning. The moon is going around the Earth the same direction, but not quite as fast so it gets left behind.

Answer 6

because the sun is still setting down.
