Bigger Moon or nature's illusion?

moon looks bigger near horizon moon looks smaller
Moon looks bigger nearer to the horizon
Moon starts" looking smaller" as it rises up in the sky
Details of the animation/ movie /software

The moon looks bigger when we see it behind tall trees or buildings and are able to make a size comparison. Our eyes are unable to adjust for the true distance of the moon from the trees and buildings, and we make our comparison as if the moon were merely a little distance behind the trees.
After the moon is up in the sky, we however have no object with which to compare its size. So it appears smaller.

The size of any object depends upon the angle they subtend at our eyes. The moon in both the cases subtends equal angle at our eyes. Its only that we see the size of objects relative to some other object.

If you are still unclear about the concepts, please refer the animation below.

Q & A
Q1: Hummmmm!! Mohammed Alhammali 31/7/2007
Ans: Welcome! but what was that ?
Q2: Hi, you guys need to correct the Currency Converter Rate or Scale concerning the Saudi Riyal comparing to US $. FOR example, 2 $ dose not equal 82.00 Riyals as you mentioned! Actually it equals about 7.5 Saudi Riyals. Best Regards Mohammed Alhammali 16/6/2007
Ans: Mr. Alhammali thanks for your response, there seems to be a confusion here, our yahoo currency conveter and CC Avenue converter puts $2 = 82 Indian RUPEES, did you mis-read this as riyals, it correctly converts Riyal (SAR) to 7.5 , rest assured we will not charge you more at any time - Best regards - Admin
