Via Wikipedia: "The Moon has an exceptionally low albedo, giving it a reflectance that is slightly brighter than that of worn asphalt." Yet, the sun is /so bright/ that even at 380,000km we see moon-shadows at night on earth.
To a first approximation, small LEO satellites are roughly the same angular size as Venus at its average distance to us.
Consider our moon is the one of the darkest objects we know of, about the color of a asphalt parking lot.
