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.

    Just being bigger isn’t enough, distance plays a factor. The moon is much, much smaller than the sun, but almost entirely covers it during a solar eclipse.
