Density of the milky way galaxy
WebA typical mass density for a globular cluster is 70 M Sun pc −3, which is 500 times the mass density near the Sun. In the solar neighborhood, the stellar density of a star cluster must be greater than 0.08 M Sun pc −3 in order to avoid tidal disruption. WebThe farthest rotation velocity so far measured for a spiral galaxy is that for the Milky Way and M31 up to ∼ 300 kpc, where the kinematics of satellite galaxies was used to estimate the circular velocities (Sofue 2012, 2013b). The obtained rotation curve was shown to be fitted by the NFW density profile.

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
