That’s an interesting point actually. If you’ve ever seen that “powers of ten” movie clip, that pans from the nuclear scale all the way out to the known universe, you’ll notice that there’s a big gap of nothing from the solar system scale, at 10 light-hours to the galactic scale, at 100,000 l-yrs. And then clusters of galaxies are only about 200 times as large as galaxies, at 200 million l-yrs or so, and then 100 times that is the universe, at 20 billion l-yrs.

So yeah, 47 million l-yrs is up there, even though it’s among the closest of all the visible galaxies.
