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 total volume of the sun is 1.4 x 10 27 cubic meters. About 1.3 million Earths could fit inside the sun. The mass of the sun is 1.989 x 10 30 kilograms, about 333,000 times the mass of the Earth. The sun contains 99.8 percent of the mass of the entire solar system, leading astronomers Imke de Pater and Jack J. Lissauer, authors of the textbook Planetary Sciences, to refer to the solar system as the sun plus some debris.
