I can not find NH's trajectory on ssd.jpl.nasa.gov and others..
Can anyone post it here? Thanks!! |

Ultimate Trajectory Question:
Will NH leave the solar system and continue outbound as Pioneer & Voyger have--- or eventually end up in a long 'comet-type' elipse around the sun? |

Using the current positon and velocity from the "where is NH" page: http://pluto.jhuapl.edu/mission/whereis_nh.php And the standard gravitational parameter for the Sun, from Wikipedia http://en.wikipedia.org/wiki/Standard_grav...ional_parameter We can figure the "hyperbolic excess" (the velocity at infinity) which I estimate at 12.7 kps. Or, in other words, "that baby's never coming back!" --Greg :-) This page has some other interesting equations: http://en.wikipedia.org/wiki/Hyperbolic_trajectory |

Using the current positon and velocity from the "where is NH" page ... http://en.wikipedia.org/wiki/Standard_grav...ional_parameter ... We can figure the "hyperbolic excess" (the velocity at infinity) which I estimate at 12.7 kps. I have used the same wikipedia page and orbital information from the SSD Horizons System to calculate the hyperbolic excess for all 5 probes at http://www.unmannedspaceflight.com/index.p...st&p=112578 16.6 km/s - Voyager 1 14.9 km/s - Voyager 2 12.5 km/s - New Horizons 11.3 km/s - Pioneer 10 10.4 km/s - Pioneer 11 Of course the value for New Horizons will change (a little) due to the Pluto flyby and KBO targeting maneuvers -------------------- |
