What is the approximate diameter of the Milky Way Galaxy listed in the structural comparison table?
Answer
100,000 light-years
The Milky Way Galaxy is identified as our home galaxy, composed of hundreds of billions of stars. When examining the scale metrics provided in the structural breakdown, its specific measurement is quantified. The approximate diameter listed for the Milky Way is 100,000 light-years. This measurement serves as the baseline reference point from which all larger structures, such as the Local Group (about 100 times wider), the Virgo Supercluster (over a thousand times wider than the Milky Way), and the Laniakea Supercluster, are measured and compared, highlighting the immense difference in scale between a single galaxy and a supercluster.
