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.

    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.
