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. |

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. |

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. 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 Neptune’s orbit”.. (Originally it was not even supposed to explore beyond Pluto–Charon; 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. 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. |

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.

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 -- PointedEars Twitter: @PointedEars2 Please do not cc me. / Bitte keine Kopien per E-Mail. |

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. You are living proof. 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? Find out where on the "celestial sphere" Pluto was in July 2015. Find out what stars are in that area. That's roughly where the spacecraft is going. 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 System’s 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. The spacecraft was launched on an Altas V that had a third stage. It reached lunar distance from Earth in NINE hours. There can't be enough fuel on the probe to do much more than deflect its trajectory slightly. |
