Actually, to fully understand the relative positions of sun, moon and the earth which causes the phases, a 3D animation is required. In 2D, the full moon phase appears as a lunar eclipse as the moon is shown "behind" the earth, although in a full moon all three of them are not in a straight line.

From 1:31 to 2:23.: On the animation the moving direction of the Moon around the Earth is wrong. The Moon moving around the Earth to the opposite direction. When the Moon stand in the first quarter you can see that the right side of the Moon is bright and the left side is dark. In the third quarter the right side of the Moon is dark and the left side is bright. The Lunar Circles begins from the '"New Moon". After this the Moon is "growing". In the hungarian language : "swells". Increasing in size of the illuminated parts. This goes completly to the "Full Moon". After the "Full Moon" the Moon is wanes: have a progressively smaller part of its visible surface illuminated, so that it appears to decrease in size. In this animation the order is reversed.

Lastly, the so called rotation of the earth is deliberately not taken into consideration cause otherwise we sholud see more than one phase of the moon every night !!! as my country's position in space every day; for example, if at 6:00 pm I see half of the moon lit, then at 4:00 pm, as the earth has rotated miles, my country's position would have been moved miles away from the moon and we should face the moon from a completely different angle and see the moon in a different phase and every single day from our country we should see the whole phases of the moon as we face the moon at all angles cause of one full rotation of the earth every single day and this does not happen at all !! Finally, then what about the lunar and the solar eclipses now!! Compare them to this model and u will know how naively we believed in such silly imaginative models. Wake up people.

27.3 days for the moon to orbit the earth, the actual time between lunations may range from about 29.18 to about 29.93 days.
@blakesnipe53478 жыл бұрын
This is because it take 27.3 days to orbit the Earth relative to the stars - but in that time, the Earth has orbited around the sun - so it takes an addition 2.2 days or so for the moon to line back up in the same position relative to the Earth and sun - for a total of about 29.5 days on average. The 27.3 day period is called the "sidereal month" - meaning _relative to the stars_, and the 29.5 day period is known as the "synodic month" - or _relative to the sun_. The same thing happens with the Earth's rotation. There is a sidereal day and a solar day. Caused by the same thing. The Earth rotates once relative to the stars (its ACTUAL rotation) in about 23 hours and 56 minutes (and change). This is the sidereal day - the amount of time it takes for the stars to reappear in the same position they were the previous day. However, in that time, the Earth has traveled in orbit around the sun, so it takes an extra 4 minutes for the sun to be back in the same position as the previous day - for a total of 24 hours - which is the solar day that our calendars are based on. If we based calendars on sidereal days, we would lose 4 minutes every day - and half the year, it would be dark at noon.

@blakesnipe53478 жыл бұрын
The moon orbits the Earth in a plane that is tilted by about 5 degrees relative to the plane that the Earth orbits the sun in. So it goes "through" the ecliptic (the ecliptic being the plane the Earth orbits the sun in) twice on each orbit. Once coming from the bottom up, and another time (about two weeks later) coming from the top down. On most full moons, the Earth is between the sun and moon, but not blocking light from the moon. A few times each year, the Earth DOES block this light giving us a lunar eclipse. These only happen when a full moon occurs at the same time that the moon is very close to crossing the ecliptic plane. The same applies for solar eclipses and the new moon. Most of the time, the moon is not in the ecliptic, but if a new moon coincides with the moon crossing the ecliptic (or very close to it), we get a solar eclipse.

That how much it changes. to further clarify, remember moon takes 28 days to go around earth and earth takes only 24 hrs to rotate around it self. just like the sun, moon too rises from the east sets from the west

In Hungarian language C) "Csökkenő" = decreasing, shrinking D) "Dagadó" = swelling, growing, etc as a kid I learnt this: when the moon looks like a letter C its "decreasing, shrinking" so going to be "dark" when it looks like a letter D its growing ... so its going to be full moon... there could be some English words too that has first letter is C and D that has similar meaning.... maybe C - Ceasing moon.... I don't know a good one for D as "growing" moon in the animation looks like it's the other way... the first "phase" he sow was a letter C so it should be the "last" (ceasing) phase...

Thank you and well done. Contrary to some of the earlier comments, this is (largely) accurate. The early part showing the Moon's and Earth's orbits were shown from a northern hemisphere POV. The latter part, showing the Moon's phases was shown from a southern hemisphere POV. (Hints: (a) The Moon is orbiting and the Earth is rotating clockwise and (b) look closely at the image of the Full Moon.) The earlier criticisms are probably northern hemisphere dwellers who are ignorant of the fact that only half of the world is seen from their perspective. The one inaccuracy is that lunar elongation is counted only from 0°to 180° (east while Moon is waxing), and then back from 180° to 0° (west while Moon is waning.)

The moon rotates, but its rate of rotation is in sync with its orbital period. In other words, the lunar day is the same length as the lunar year because it is tidally locked with the Earth. If you were on the moon, you'd see the sun (and stars) rise and set every 27.3 days. It also takes the moon 27.3 days to orbit the Earth, so by the time the moon has rotated 90 degrees around the Earth, it has also rotated 90 degrees in the same direction, showing us the same face. So on and so on.
@JacobHayden9118 жыл бұрын
The Moon is tidily locked with Earth. Which means only one side of the Moon faces Earth. The Moon kinda rotates. Ever time it finishes an orbit, technically, it has spun all the way around, but not in one position. So the Moon is tidily locked so you always see that one face. :) Answered?

The relative position of the sun and moon are closely monitored. The short answer to your question is - you didn't see what you are claiming to see - or you didn't see what you think you saw. When the moon is exactly half lit, the sun and moon should be about 90 degrees apart in the sky. Since you can see pretty much 180 degrees of the sky at a time, it is possible and even likely that the sun and moon will be out during the day at the same time. I wonder what you mean by "close to each other". Again, if you want to claim that they were 10 degrees apart and you saw half the moon lit, then you didn't see that. It didn't happen. Again, these things are tracked.

First off, the Earth rotates and orbits the sun in a counterclockwise direction; not clockwise. Of course, this is really arbitrary - it's just that most astronomers would define the direction of rotation from the top looking down - and from that perspective, the motion is counterclockwise. However, if you viewed the system from the bottom, it would be clockwise - and just as valid a description. For our purposes, we will use the top-down perspective and call it counterclockwise. And the reason : Because the angular momentum of the system is conserved. Before the solar system formed, the entire system had angular momentum in a counterclockwise direction. Because of this, all the planets orbit in a counterclockwise direction - as well as rotate in a counterclockwise direction - except Venus. It is thought that Venus DID rotate in a counterclockwise direction, but was hit by something that knocked it "upside down" - it's still rotating the same direction it always was, it's just flipped over.
