Moon's size from Earth's surface and viceversa.

[alvarezp]

I post it as a bug, though not sure if it is.

Say I go to Earth at 0.2km altitude and then I look at the moon. I'm not able to see the moon as seen from here. In my opinion it should look bigger. Don't know how much, though.

From another point of view (literally ), I try to imagine myself in the Moon, looking at the Earth. If the Earth is six times bigger than the Moon, [the Earth] it should look six times bigger than the Moon look from here, which should be rather big!

The same could be applied to the Sun.

[Edited to post more info] Technical details about my PC: Windows 2K SP0, with Matrox Mystique video card. It happens this with the on-board SiS 530 too.

Thanks.

alvarezp,

Do not forget to adjust the degree's of the camera angle. The default is 45 degrees. To get the effect you are looking for increase the field of view to around 15 or so( not at my home computer so it is probably off). To change the field of view I believe it is the < and >. < increases it and > decreases it. How do you think they get those wonderful shots of the triple eclipse on Jupiter, the angle for that is in the seconds!!

Hope this solves the problem.

The moon is correctly sized in Celestia. (If you've ever taken a photograph of the moon with a standard camera, you'll have experienced the same disappointment at how tiny it appears in the photograph.) Entire books have been written about the optical illusions that make the moon appear bigger than it actually is, especially when viewed near the horizon.
Next time there's a full moon, do this little test - choose a coin from your pocket that you think will be the same size as the moon when held at arm's length; when you try it out, you'll usually be astonished at how much bigger the coin is than the full moon. (The matching coin would be less than a centimetre across.)
