Physical Characteristics
Himalia's rotational period is 7 h 46 m 55±2 s. Himalia appears neutral in color (grey), like the other members of its group, with colour indices B-V=0.62, V-R= 0.4, similar to a C-type asteroid. Measurements by Cassini confirm a featureless spectrum, with a slight absorption at 3 μm which could indicate the presence of water.

Famous quotes containing the word physical:
“It seems to me that we have to draw the line in sibling rivalry whenever rivalry goes out of bounds into destructive behavior of a physical or verbal kind. The principle needs to be this: Whatever the reasons for your feelings you will have to find civilized solutions.”
—Selma H. Fraiberg (20th century)
