Cover the Moon with your thumb when it is close to the horizon. Repeat the exercise several hours later. Compare. |

nomuse (NLI) User ID: 610185 United States 02/10/2009 05:24 PM Report Abusive Post Report Copyright Violation | You have to envision the Earth/Moon system from above to get the geometry of it. Imagine, here is the Earth in the middle of our diagram, the Sun is to the right of the diagram, the Western hemisphere is pointing to the right so that the Sun is directly over Texas. Now draw the Moon on the same diagram, above the Earth, so that to the guys and gals in that great state the Moon is sitting on the horizon. As you will see, both the Moon and the Earth are half in the light, half out of the light. You are in the half of the Earth that is lit (assuming you are from "Big D," I mean Dallas). However, you are looking at the SIDE of the Moon, and you see half of it lit, and half of it not. It's clearer with a diagram, but I thought I'd try it in words first. Besides...there are a million of those diagrams out there. If you've already seen them, and didn't get it, then maybe words are best for you. |

Quoting: Anonymous Coward 588041Sorta. The phase of the Moon is DIRECTLY related to the visual distance between it and the Sun. A crescent Moon MUST be near the Sun. If the Sun is just setting, and the Moon is at the Zenith, even without looking up you know the Moon is in a quarter phase. And a full Moon MUST be 180 degrees from the Sun. Which means it rises as the Sun sets, and sets as the Sun rises; you will never see them both in the sky at the same time. I'm not saying you are wrong.

Seriously, shouldn't a round object be fully illuminated when a direct light is on it? the earth blocks the light.. the end. The Earth does not block the light to or from the Moon. If it did it would be an eclipse, there are as many degrees of eclipse as there are phases to the Moon. Now back to astronomy 101, The Moon orbits the Earth. That means it goes around the Earth. As the Moon is orbiting the Earth the Earth is orbiting the Sun. Different perspectives of the Moon from an Earth based viewer are possible. The Moon while part of it is always full from the Sun side only shows phases with respect to Earth. A person may see only a phase of the Moon (i.e. half) that does not mean the Earth is shadowing the other half. It does mean that from a vantage point on Earth we only see half of the Moon lit. From a vantage point outside of the Earth it is still a full Moon. The dark half that you see as an observer is from the shadow of the Moons own making.. ...Do You Even Couth, Bro...

Czarlon User ID: 612155 United States 02/10/2009 06:11 PM Report Abusive Post Report Copyright Violation | That is partially true. The Sun and Moon always share the same side of Earth's sky except on the day of a full moon, when they are 180 degrees separated. The day after a full Moon, (actually it happens almost instantly) then the sun starts to light the other side of the Moon. That is why the crescent Moon faces one way and then the other. ...Do You Even Couth, Bro... A person often meets his destiny on the road he took to avoid it. Jean de La Fontaine |

The link you posted doesn't refer to that acquisition, in fact that link doesn't even mention the Horizon. Please try to keep up with the discussion at hand! Ok I digress, you are right. Let me see if I can explain. When the Moon is near the horizon the light from the Sun reflecting onto the Moon is seen through more of the Earth's atmosphere. What happens is as you look through the atmosphere there is water vapor there. This water vapor acts as a refractive lens which in turn magnifies the apparent size of the Moon. It is just an optical illusion. The size of the Moon does not really change. ...Do You Even Couth, Bro... A person often meets his destiny on the road he took to avoid it. Jean de La Fontaine |

The Moon has to be EXACTLY full for the condition I described to apply. And it isn't EXACTLY full for even the length of an evening (moves, what, 1 1/2 times it's own diameter each night?) However, since most location have some degree of obstruction on their horizons (around here, it's a set of hills to the East that cut off the first 15 degrees of sky), practically speaking, on the night of a full Moon you will not see the Sun in the same sky. |
