That would be as if the Sun stretched from the horizon 2/3 of the way up to the zenith.Steven Schimmrichhttps://www.blogger.com/profile/12055292815320443096noreply@blogger.comtag:blogger.com,1999:blog-1644183700798263875.post-44773744728553418532013-11-29T11:40:34.975-05:002013-11-29T11:40:34.975-05:00Interesting.

The graphical comparison of the Sun's angular size is really impressive.<br /><br />Due to my calculations, the angular size of Sun from the nearest star (Proxima Centauri) is ca 0.007 seconds of arc. Not much, to say the least.Maxnoreply@blogger.com
