Sure, but nothing will encounter or observe them ever again.
Things we put into heliocentric orbits are likely to be forever, too.
> Along a similar vein many of the satellites that we put in graveyard orbits around earth at the end of their useful life will also plausibly last that long, though there is a lot more debris for them to collide with.
While they won't decay from drag in a few million years, tidal forces and photon pressure become significant over time.
