If its a total lunar eclipse why does one edge remains brighter than the rest?

I have been googling for an answer for a while and cant find it. Even pictures of previous total lunar eclipses are the same. Is it because that side remain closer to the edge of the umbra? Or is it caused by how light behaves; Or because the surface of the moon is more reflective on that part.

For a solar eclipse, to my knowledge, it's just a happy accident that our moon is pretty much the right size to block out our sun. Isn't that neat? A solar eclipse on every other planet in the solar system would end up being much less interesting.

Sorry, thats not my question. I misstyped solar instead of lunar so I take the blame.

But I agree that its quite amazing how perspective wroks between the sun, earth, and the moon. Earth is also the right size tho block out the sun the same way when viewed from the moon. Would be hard to believe if we werent experiencing it tbh.
