Hello, I've made a SPK file for the asteroid 7482 (1994 PC1) with Horizon. I wan't to change the inital velocity with cspice, because I want to know where it will be in a future time at that speed. Now I'm using newtons calc for NEO asteroid, but is slow an error increases with time, and cspice for solar system. This is for calculating NEOs asteroid desviation by gravity tractors, so if you now another way to do it let me know, please.
Thanks
Thanks
