Sizes of Galaxies

This chart illustrates a comparison of the sizes of various large galaxies. While the Milky Way is considered averagely large, boasting a diameter of 100 000 light years and hosting an estimated 200 billion to 400 billion stars, it appears dwarfed when compared with larger galaxies such as M100, M87, NGC 4921, or Hercules A. For a comprehensive overview, Sun.org features an additional chart showcasing the biggest known galaxies, including the colossal IC 1101, which would exceed the size of this entire image.
