In comparison with what we discover in our Photo voltaic System, galaxies are actually monumental.
The smallest identified galaxy is Segue 2, with solely about ~1000 stars inside.
These stars are unfold out over ~500 light-years: billions of instances the bodily dimension of any particular person star.
Galaxies can get a lot bigger, however many “relative dimension” depictions 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.
However interacting galaxies can change into tidally disrupted, vastly rising their extent.
The Tadpole galaxy’s tail alone is 280,000 light-years lengthy.
In the meantime, UGC 2885 is our largest spiral: 832,000 light-years in extent.
Elliptical galaxies, nevertheless, are the biggest galaxies of all.
Messier 87, the Virgo supercluster’s largest galaxy, is 980,000 light-years throughout.
The Coma Cluster’s largest, NGC 4889, spans 1,300,000 light-years in diameter.
In the meantime, the Phoenix Cluster’s brightest central galaxy measures 2.2 million light-years throughout.
However the largest certainly one of all? That’s IC 1101.
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.
