Default New Horizons "stellar" course?

Cannot find this information anywhere, but curious where New Horizons
would be heading in the long term, in other words what star? And also
are there any more visits to other objects planned besides the latest?
Thank you.

[Which information? Your question belongs *in the posting*(, too.)]

Are you serious?

First Google result (of “About 122.000.000 results (0,49 seconds)”)
for the keywords “new horizons”:

https://www.nasa.gov/mission_pages/newhorizons/main/

“Mission Overview”
→ https://www.nasa.gov/mission_pages/newhorizons/overview/

“Johns Hopkins' Applied Physics Laboratory”
→ http://pluto.jhuapl.edu/

The next result is the mission’s Twitter profile…

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.

In which of those 122,000,000 results did you find the answer to JBI's honest question?

Different from the Pioneer and Voyager probes (and the future Project
Breakthrough Starshot), New Horizons is (currently) not supposed to leave
the Sol system in the first place, but to investigate Kuiper Belt objects
at least a billion miles beyond Neptunes orbit. (Originally it was not
even supposed to explore beyond PlutoCharon; the Kuiper Belt mission is
already the mission extension).

Read the mission description before you jump to conclusions (extrapolate a
trajectory) only from a *current* heading.


The thing is heading OUT of the Solar System on an interstellar trajectory.


Repeating nonsense does not make it true. That the *current* heading of NH
is away from Sol does not mean that it has to be so *in the future*. And it
does not mean that it is heading towards any particular other star. Not
only was it never supposed to, but, put simply, space is big.

How did you get this idea of in the general direction of Xi 1,2 Sagittarii,
less than a degree to the east of those stars, perhaps anyway?

Its current heading is approximately the same one it had after it had passed
Pluto-Charon in July 2015. Unless it hits something substantial, it's gone.


We will see. Ultima Thule is 43.23 AU away from Sol. The Kuiper Belt is
estimated to have a radius of 50 AU. The termination shock is at 75 AU to
90 AU. The heliopause is at 120 AU. The Sol Systems Hill sphere has a
radius of up to 3 ly. NH does have 4 4.4 N thrusters for trajectory
corrections; the Voyagers had only 4 0.89 N each.


Once again this has nothing to do with amateur astronomy; except of the fact
that several astronomy amateurs here are actually attempting to teach people
who are studying or have studied astrophysics

Think before you post.


Likewise.

Whether or not its nearly linear path lines up closely enough to any additional
objects that it can study them is a matter of luck.


You mean probability.

Its trajectory is hyperbolic; it WILL leave the Solar System,
and there's no way to change that.


Incorrect.

It was always understood that its trajectory would cause it to do so.


Since we have almost no idea what is in the Sol System beyond Ultima Thule,
this is not only an unfounded, but utterly ridiculous claim.

It is the purpose of this mission extension to investigate the Kuiper Belt,
not to make an interstellar probe out of NH.
