A Plane not A Planet
If the moon is 238,000 miles away , how big is the smallest crater we can see with the naked eye ? And should we be able to see it , if the distance of 238,000 miles is correct ? I suspect not .
At about the 3:50 mark in the daylight moon video, they suggest that if the sky was red, that would also be the colors of the craters. This is actually the right answer, yet they failed to stop and consider why.
The moon at night is seen in/through a black sky, and the moon above is seen in/through a blue sky. The lighter portions of the moon are reflecting the sunlight, but the darker craters aren’t.
With no light coming from the craters, what you then see is the color of the sky you are looking through. The lighter portion is also shaded a bit during the day due to the blue sky we are viewing it thru. At night, there is no shading, just the bright white reflection.
As for the bottom left portion of the moon not lit be the sun; just follow the camera direction between the sun and moon as they move it side-to-side. The part of the moon farthest from the sun is the bottom left portion. Since we can’t easily calculate the angles involved, we don’t easily know how to determine the light/dark proportions. Nonetheless, we can trust our eyes to see the shading, and understand how the positions can produce the effect.
