Albedo of a comet - what does this mean: 4 examples

Images of Enceladus, the Earth, the Moon, and Comet 67P/C-G, with their relative albedos scaled approximately correctly. The albedos that were used are: 100% for Enceladus, 31% for the Earth, 12% for the Moon, and 5% for 67P/C-G. The images are not however to scale physically. The image of Earth was taken by the OSIRIS camera on Rosetta during the spacecraft’s last flyby past our planet in 2009.The Advantage is the same system photographed both the earth and the comet reducing systematic calibration effects. Look carefully - the comet is THERE! You might be interested in following this further.
