Even outside the solar system there are still some particles about, most of which are moving at high velocities.
At a minimum, I would expect it to look quite thoroughly sandblasted after 16 million years.
- bombcar 5y agoI suspect the size of the particles and number is very very low - effectively zero once you're far enough away from the Oort Cloud.
- Turing_Machine 5y ago> I suspect the size of the particles and number is very very low The number is indeed low, though the size can be anything from a molecule to full-sized planet. On the other hand, 16 million years is a very very long time, and 17 km/s (the current velocity of Voyager 2) is a respectable velocity. Even small particles will take the "new" right off something at that velocity. By comparison, the velocity of a 5.56 mm rifle bullet is only about 1 km/s.
