Mass
In 2005, Emelyanov estimated Himalia to have a mass of 4.19×1018 kg (GM=0.28), based on a perturbation of Elara on July 15, 1949. JPL's Solar System dynamics web site assumes that Himalia has a mass of 6.7×1018 kg (GM=0.45) with a radius of 85 km.
Himalia's density will depend on whether it has an average radius of about 67 km (geometric mean from Cassini 2000) or a radius closer to 85 km.

Famous quotes containing the word mass:
“Self-determination, the autonomy of the individual, asserts itself in the right to race his automobile, to handle his power tools, to buy a gun, to communicate to mass audiences his opinion, no matter how ignorant, how aggressive, it may be.”
—Herbert Marcuse (1898–1979)
“A serious problem in America is the gap between academe and the mass media, which is our culture. Professors of humanities, with all their leftist fantasies, have little direct knowledge of American life and no impact whatever on public policy.”
—Camille Paglia (b. 1947)
“It is a mass language only in the same sense that its baseball slang is born of baseball players. That is, it is a language which is being molded by writers to do delicate things and yet be within the grasp of superficially educated people. It is not a natural growth, much as its proletarian writers would like to think so. But compared with it at its best, English has reached the Alexandrian stage of formalism and decay.”
—Raymond Chandler (1888–1959)
