In comparison with what we discover in our Photo voltaic System, galaxies are actually monumental.

Galaxies can get a lot bigger, however many “relative dimensiondepictions are inaccurate.

Our personal Milky Manner, typical of recent spirals, is barely over 100,000 light-years throughout.

Andromeda’s diameter is roughly double ours: 220,000 light-years.

Half the sunshine is contained inside a 2 million light-year central radius.

Its full span is 5.5 million light-years throughout: almost double the Native Group’s full extent.

The true relative dimension variations spotlight galactic range.
