NASA’s New Horizons spacecraft flew by Pluto this morning and is now heading deeper into the region of space called the Kuiper Belt, where there are rocks, asteroids and comets leftover from the formation of our solar system that didn’t get pulled in by the process of accretion by the sun to make planets.

And beyond Eris, is the heliopause, a region of space where the sun’s gravity influence ends and the entry to interstellar space begins.
