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.
