Largest spiral galaxy known.
Arata:
What is the largest spiral galaxy known and what is it's size?
I hear that the largest Is NGC1232, and it's around 200 000 light years across.
But we are 1 500 000 light years across, and it would take 7 1/2 NGC1232's to cover our own galaxy, so wouldn't we be the largest spiral galaxy known to man himself?

Arata, I don't think we're sure that our galaxy is so big yet. But ofc you're welcome to prove me wrong...
monmarfori:
Malin 1. 650000 light-years it alots 1/16 to cover

Well, compared to the universe, its not really that large, but if you were to compare us to the largest galaxies known, it's seems larger than you think.
Dan Dixon:
Our galaxy, the Milky Way, is 100000 light years across.

This page says that NGC 1232 is 200000 light years across.

So NGC 1232 is only twice as wide as our own galaxy.
Where did you hear that NGC 1232 is the largest? I couldn't find anything after a few minutes of searching.
