    Isn't it an optical illusion of some kind? I'm sure I read once that when it is high in the sky, there are no points of reference nearby and so it appears smaller than it is. Something like that anyway...??

    An amateur astronomer friends of mine said the size of the moon is the equivalent of a hard boiled pea held at arms length. Now I have no idea why it has to be hard boiled!:confused:

      Why is it that the moon sometimes look much bigger than other times? Is it because of the atmospheres curvature (acting like a magnifying glass)? -- You know me. I sure know you.. Everyone of you!

      It's because of atmospheric refraction. When the moon is low on the horizon, its light passes through more atmosphere, which acts as a magnifying lens. As it rises, the apparent size decreases. Or so I read once upon a time.:-O

          Yeah its an optical illusion. Apparently you can verify that by viewing the moon through a cardboard tube or a hole on a piece of paper ( blocking out the surrounding), at different times. Or you could actually measure it with a ruler and see if it changes.... --------------------------------------------------

            I was walking outside and realized for the first time in my life that "Darn ! That moon must be **huge** to appear that big at this distance !" ..I felt it was a thing to be shared. F.O.R.

            No, it's not really that big, it's painted on your eyes. Actually, the whole world is painted on your eyes, by those japanese artists that paint entire murals on a cherry stone. The, you#re trained in selective perception for 3..4 years. That's why your first memories start that late. :cool:

              I live in surrey (near the south of england) and the moon appears a certain size pretty much all the time, my parents live 600 miles north, in scotland near inverness. I went to vist them one christmas and took a look at the moon, it seriously looked like something out of starwars, it was over twice the size than I have ever seen it before. Kinda wierd really, I would expect this if i was sat on the north pole, but not in scotland. Oh well... James Simpson Web Developer imebgo@hotmail.com

              Without checking beforehand, which object when held at arms length, is the smallest that will completely cover up the moon when it is full? 1) A quarter 2) A nickel 3) A dime 4) A pea 5) A BB The answer is 5! The moon appears larger when near the horizon because we subconsciously compare it against the objects near the ground.

                Yes. Isn't it strange that we take so many things for granted, especially those that we grew up with. Thanks for sharing. :) It's cloudy here, or I would have gone to take a look too, after your post.

                      ...hmm... I don't think that the distance Earth Moon is constant anyway... Plus, I'm sure that the atmospheric conditions have something to do with it... F.O.R.
