The largest known galaxy is IC 1101, but it is vert faint in the sky due to its distance from us.


IC 1101 in Virgo has a effective radius of about 212000 light years.
It is at a distance of 1 billion light years from us, so it appears relatively small and cannot be seen without a very good telescope.
