Physical Characteristics
Although its size has not been directly measured, the moon has been calculated to have a diameter of between 46 km (if its geometric albedo is similar to Charon's 35%) and 137 km (if it has a reflectivity of 4%, like the darkest Kuiper belt objects). Nix is slightly fainter than Hydra, suggesting that it is somewhat smaller in size. In the discovery image, Nix is 6,300 times fainter than Pluto.
Early research appeared to show that Nix was reddish like Pluto and unlike the other moons, but more recent reports have been that it is grey like the remaining satellites.

Famous quotes containing the word physical:
“[In early adolescence] she becomes acutely aware of herself as a being perceived by others, judged by others, though she herself is the harshest judge, quick to list her physical flaws, quick to undervalue and under-rate herself not only in terms of physical appearance but across a wide range of talents, capacities and even social status, whereas boys of the same age will cite their abilities, their talents and their social status pretty accurately.”
—Terri Apter (20th century)
