there's something very puzzling about this picture, that seems to call for some fact checking

I mean, it's a great coincidence to begin with that the moon and the sun have the same apparent sizes when seen from the earth in solar eclipses

but the earth is significantly bigger than the moon, and the moon is as far away from the earth as the earth is from the moon, so the apparent size of the earth as seen from the moon should be bigger than that of the moon as seen from the earth

but the earth seems slightly smaller than the sun in the picture, and it's not like the moon is closer to the sun than the earth is to justify this discrepancy by seeing an apparently bigger sun

ISTM that it's too much of a coincidence that the apparent size of the earth would be as close to that of the sun as seen from the moon, on top of the coincidence that the apparent sizes of the moon and of the sun are about the same when seen from the earth.

it's not absolutely impossible, but the moon orbit would have to be just weird enough to make for this coincidence just at the time of the eclipse that I'm having trouble believing that.

can anyone offer evidence that the compounded coincidence is indeed plausible, and that the picture isn't a fake? I could more easily believe it's a picture of an earlier solar eclipse seen from the earth, or some AIrstistic rendering of a solar eclipse as seen from the moon misgeneralized from pictures of solar eclipses taken from the earth
