Mass, Size, and Density of the Universe. The mass density of visible matter (i.e., galaxies) in the Universe is estimated at 3e-28 kg/m^3 (3e-31 times the mass density of water). The radius of the visible Universe is estimated at 1.7e26 m (18 thousand million lightyears) plus or minus 20 percent or so.
The above mass is about 7005332946000000000â 332946 times the mass of the Earth (M â), or 7003104800000000000â 1048 times the mass of Jupiter (M J). Because the Earth follows an elliptical orbit around the Sun, its solar mass can be computed from the equation for the orbital period of a small body orbiting a central mass.
