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!"

This page has some other interesting equations:
