As the Moon is a cresent, why does Venus appear round?
Perhaps because the Moon is generally between the Earth and the Sun, an Venus is perhaps to the left and on the other side of the Sun?
Ah... the site says Venus is beyond the solar limb...
Venus looks completely round and the moon a sliver of a crescent. What does that tell us?
The sun is almost completely behind the moon (from Earth) and almost exactly in front of Venus (from earth), so Venus is on the far side of the Sun in its orbit, not the same side of the Sun we are on in our orbit. It’s something like the opening scene of “2001: A Space Odyssey” but with Venus Sun Moon Earth.
You may say, then why don’t I see the Sun? The angular size of the moon is only about half a degree from Earth. The Sun is not far out of the shot.
