Albedos of four Solar System Bodies

Explanation: From top left corner, clockwise: Saturnian moon Enceladus, Earth, Comet 67P/C-G, and the Moon. While images of celestial bodies are generally adjusted to have a brightness and contrast that best show surface features, these images have been scaled to show how the abledo of each body compares. Albedo is the term for the percentage of light reflected by each body. Note that Comet 67P/C-G is so dark it appears black! The albedos for Pluto and Charon fall somewhere between the Earth and Enceladus, with Charon being a bit darker than Pluto and closer to the reflectivity of Earth. The albedo of Pluto varies greatly with its rotation period. The albedo of Ceres is slightly darker then that of the Moon but brighter than that of Comet 67P/C-G.
