I got a question at Wikipedia regarding the geometric albedo of Enceladus. Verbiscer et al. 2005 reported that Enceladus geometric albedo at 555 nm was 1.41, greater than unity. This is much greater than the 0.99 reported in Verbiscer and Veverka 1994. The 0.99 figure was listed in Wikipedia until the release of the Porco et al. paper on Enceladus, which cited the Verbiscer et al. 2005 paper when mentioning the visual geometric albedo (1.4 in the Porco et al. paper).

So someone on Enceladus' wikipedia talk page has asked how can Enceladus have a visual geomtric albedo greater than 1. I thought I would direct the question here.
