The event horizon of this black hole is ~1600 astronomical units, or nearly 32 times the distance from the sun to Pluto. This is close to the diameter of the entire solar system. Voyager 1 has so far traveled a distance about 10% of the diameter of this black hole.
Another[0] black hole relatively close to Earth has an event horizon diameter 14 miles wide.

Duh! Thanks.
But we usually don’t speak that way about things that might be thousands or millions of light years away but I bet at those “small” scales the difference might be negligible in conversation.

According to the wiki article, the quasar is 16 bn light years away, but the light we see from it is only 10 bn years old?
