I was wondering if is would be possible for a spacecraft to visit the "interstellar immigrant" 2015 BZ509? I would think this would be a very exciting opportunity to visit something from outside our solar system that is in orbit(retrograde) around the sun.

Unless its just a high velocity flyby, a Jupiter swing-by would be pretty much mandatory, without prodigious fuel needs or sci-fi propulsion methods. Ulysses did one in 1992 to change its inclination to polar; presumably a second would be needed to start going retrograde? It would take many years to do so if one gravitational assist can't do the work (some more discussion here; https://www.centauri-dreams.org/2018/05/22/...stellar-system/ ) They mention Halley's comet, which is also retrograde. I wonder what might be feasible by 2061....
