Density of the milky way galaxy
WebThe star density in the wider solar neighbourhood beyond 10 parsecs is not perfectly uniform. The most conspicuous variations occur in the z direction, above and below the plane of the Galaxy, where the number density falls off rapidly. This will be considered separately below. WebDensity is just the mass of an object divided by its volume. Although density is usually given in terms of the unit kilograms/meter3, in astronomy we prefer to use the number of particles per cubic meter. It is easy to imagine how a cubic meter might contain 1000 atoms, but the equivalent density of 1.6x10-24 kg/m3 seems mysterious and
