Which two galaxies are identified as the dominant members of the Local Group?
Answer
Milky Way and Andromeda Galaxy (M31)
The Local Group is characterized by two primary gravitational anchors that contain the vast majority of the group's mass and luminous galaxies. These two dominant structures are explicitly named as the Milky Way, our home galaxy, and the Andromeda Galaxy, which is identified as our largest nearby neighbor. Although the Triangulum Galaxy (M33) is the third-largest spiral, it is described as a companion to Andromeda and significantly less massive than the two primary members. The overall structure is heavily unequal, being dominated by the influence of these two giant spirals.
