NASA’s New Horizons spacecraft conducted the first and only exploration flyby of the Pluto system, culminating at the closest approach of that distant world in July of 2015.

Sailing onward, the vehicle carried out a January 1, 2019 flyby of Arrokoth, a Kuiper Belt Object, or KBO, located in a region of space beyond Neptune called the Kuiper Belt. There could be scads of other icy worlds residing in the Kuiper Belt, celestial leftovers from the formation of our solar system.

For New Horizons, the gathering of more exploration science is, pun intended, on the horizon.
