How does the New Horizons mission team intend to target additional objects in the Kuiper Belt, and how will the craft approach them after the Pluto system encounter?

While there is an incredible dispersion of orbits for objects in the Kuiper Belt, only an extremely small fraction of those bodies are potential targets for the New Horizons spacecraft. That’s because the fuel available for a post-Pluto trajectory change maneuver (which we call “TCM”) will allow the craft to fly by Kuiper Belt objects (KBOs) whose orbits bring them within only approximately 0.5° of the current New Horizons spacecraft trajectory.
