Huh. And here I thought the moon took the honors. Goes to show you learn something new every day on FR.
Enceladus has an albedo of .99 - it don't get any higher than that!!
Our Moon is actually quite dark. It only seems bright in comparison to the surrounding sky. Venus is far brighter, as are several other objects including Europa and Enceladus.
albedo... n : the ratio of reflected to incident light
So the albedo of a celestial body isn't a measure of the total brightness of the body, but a measure of its reflectivity as a percentage of incident radiation. Thanks for bringing this up!... I learned something today, too. :-)
