Thank you.
It seems to be heading in the general direction of Xi 1,2 Sagittarii, less than a degree to the east of those stars, perhaps.

Thank you, the information I was looking for.

So you believe blindly everything that you read?

Maybe you have a better estimation of where this spacecraft is headed?

(Hint: It will exit the Kuiper Belt in a few years. And keep going.)

Certainly. But it does not appear to have a name, or a designation
(apparently it is not even in the Hipparcos Catalogue).

If it helps, it is a star belonging to Sgr, color index (B−V) 0.98
(something between spectral class K0V and M0V, so I guess a main sequence
red dwarf), that has the equatorial coordinates (J2000.0-based)
α = 18h59m12.86s and δ = −20°49'35.1" (J2000.0-based; figures from Stellarium).

This is using your assumption, which may be wrong, that the heading of NH
has only insignificantly changed since the Pluto flyby.

Pluto has α = 18h59m16.36s and δ = −20°45'26.9" then (∆ ≈ 0°4'12.88"), while
ξ1 Sgr, which of the two ξ’s is closest on the celestial sphere to Pluto,
has α = 18h57m20.48s and δ = −20°39'23.0" (∆ ≈ 0°27'46.07").

(Hint: It will exit the Kuiper Belt in a few years. And keep going.)

Maybe. That depends on *several* *unknowns*.

IOW, in the general direction of Xi 1,2 Sagittarii, a little bit east.

There isn't enough fuel on board to keep it from leaving the Kuiper Belt and heading out into interstellar space, never to return. Unless, it were to hit something heavy enough to stop it. But as you said, "space is big."

Too imprecise. Consider the distances. In the worst case, you can fit
approximately 7 × 10¹² potential planetary systems like the Sol System, each
with at least one star, into the volume of the cone between those directions.

Repeating something which *might* be true does not *make* it true either.

Too imprecise for what?

Consider the distances.

Proper motion and radial velocity will render any precision that you demand irrelevant, given how long it will take to probe to travel the hundreds of light years involved.

So you think that there IS enough fuel onboard to keep it in the Solar System?

Or that it wouldn't be stopped by a massive-enough Kuiper Belt Object that was directly in its path?

No, I actually confirmed this same information after my initial post and
the reply here. I was waiting for a legitimate reply before I
responded, not something rude or condescending like yours. The idea was
to get a *ballpark* figure to share interesting calculations, such as
travel time to, say, that star, assuming no course or speed changes,
which would be highly unlikely of course.

Most non-astronomers don't have any idea of stellar distances and, if
there is interest, I like to express those distances in terms they can
understand. Someone was asking me where the probe was headed after its
current studies and it wasn't easy to find the answer. Sometimes Google
provides so many hits that it doesn't help in finding a fast answer
which, of course, you already knew I'm sure by the nature of your
initial response. The first place I checked was the probe site itself
and was unable to find it; from there other sources until I myself found
the answer on Wikipedia, then confirmed here and then a few more
sources. Again, the idea was *ballpark* assuming hypothetically no
changes, not precision.

BTW, any more snide remarks, I simply won't respond because I don't have
time to waste.

No comment.
