Characteristic Measurement Diameter 220,000 - 250,000 light-years Mass Approximately 1. Because of their similar sizes and the vast distances between stars, the stars themselves will likely pass through each other without direct collisions.
Andromeda Galaxy Diameter Amateur Observation: Estimating the Cosmic Giant's Size
While the Milky Way contains hundreds of billions of stars, Andromeda likely houses over a trillion. This halo can stretch hundreds of thousands of light-years further, but the dense concentration of stars defines the primary diameter.
This immense span makes Andromeda significantly larger than the Milky Way, which spans roughly 100,000 to 120,000 light-years, positioning M31 as the largest member of the Local Group. 5 billion years, the Milky Way and Andromeda are destined to collide.
