It's consensus that the very similar apparent sizes of the Moon and the Sun as seen from Earth is a coincidence (as already answered in this site). This provides us with almost exact total solar

3 The sun, moon, earth (and so on) all move around each other. The reason we say the earth moves around the sun is because the effects are more visible on a macro scale, and easier to predict with reasonable precision.
15 If it is really between the earth and the sun it is called a "solar eclipse" and and the moon's shadow falls on the earth at certain places, because it is not large enough to cover the whole sun except on a shadow path. A total solar eclipse occurs when the Moon completely covers the Sun's disk, as seen in this 1999 solar eclipse.
Why can we see the moon when it is between the Earth and the Sun?
The Sun and Moon seem to have the same size because of this amazing coincidence: the moon is 400 times smaller than the Sun and 400 closer than the Sun. Checking 400 from this source:

I want to know how much lux the sun emits on a bright day - I don't mean when one stares directly at the sun, but rather when one walks casually outside when the sun is shinning brightly. Now the
