Question

Quizplus · Accepted Answer

Studies suggest that most of the mass in the Milky Way Galaxy is located in the halo, which surrounds the disk of the galaxy and is made up of dark matter. The stars in the spiral arms and the disk itself contribute to the total mass, but they are not the main component. The central bulge also contains a significant amount of mass, but it is still less than that of the halo. Gas and dust make up a small fraction of the total mass.
