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.
