Solar Eclipse and Body With Atmosphere
Date: Winter 2011-2912
What would a solar eclipse look like if the moon had an atmosphere?
We see that effect during a lunar eclipse
When the Earth is interposed between the Sun and the Moon.
It will be a black disk with fuzzy edges. You may see some dark red
due to atmospheric refraction.
Check it out when you see the next lunar eclipse.
Good question. If the Moon had an atmosphere, it would not change things
much. A partial eclipse might begin with a few seconds of fuzziness
before the Moon's body took its first bite out of the Sun; that is
about it I think!
