Universal Gravitation for Spherically Symmetric Bodies. The Law of Universal Gravitation states that the gravitational force between two points of mass is proportional to the magnitudes of their masses and the inverse-square of their separation, d d: F = GmM d2 (5.5.2) (5.5.2) F = G m M d 2.

The halo's greatest concentration is at its center, where the cumulative light of its stars becomes comparable to that of the disk stars. This region is called the (nuclear) bulge of the Galaxy; its spatial distribution is somewhat more flattened than the whole halo.Such plots suggest that the dark matter is found in a large halo surrounding the luminous parts of each galaxy. The radius of the halos around the Milky Way and Andromeda may be as large as 300,000 light-years, much larger than the visible size of these galaxies.
