Abbreviations: GNP/GSP: Galactic North and South Poles. The Milky Way is approximately 890 billion to 1.54 trillion times the mass of the Sun in total (8.9 × 10 11 to 1.54 × 10 12 solar masses), although stars and planets make up only a small part of this. Estimates of the mass of the Milky Way vary, depending upon the method and data used.

Marked location of the Galactic Center. The Galactic Center is the barycenter of the Milky Way and a corresponding point on the rotational axis of the galaxy.
List of stellar streams. This is a list of stellar streams. A stellar stream is an association of stars orbiting a galaxy. It was once a globular cluster or dwarf galaxy that has now been torn apart and stretched out along its orbit by tidal forces. [1] An exception in the list about Milky Way streams given below is the Magellanic Stream ...
The Dark Energy Camera captured a rarely seen celestial phenomenon in action: a cosmic cloud called “God’s Hand,” which appears to reach out for a spiral galaxy.
Group of at least 80 galaxies of which the Milky Way is a part. Dominated by Andromeda (the largest), the Milky Way and Triangulum; the remainder are dwarf galaxies. Local Sheet: 7 Mpc 2.16×10 20: 20.33: Group of galaxies including the Local Group moving at the same relative velocity towards the Virgo Cluster and away from the Local Void.
