What is the estimated span across the Milky Way galaxy?
Answer
100,000 light-years
Astronomical estimations place the diameter or span of the Milky Way galaxy at approximately 100,000 light-years across. This immense scale is a crucial parameter used when constructing models of the galaxy's overall morphology. It is important to contrast this figure with the location of our own Solar System, which is situated much closer to the center, roughly 25,000 to 27,000 light-years away from the crowded central bulge. The comprehensive size measurement is derived through sophisticated mapping techniques that synthesize data gathered across various wavelengths.
