Artist's Concept of Kuiper Belt Object Encounter
Artist's impression of the New Horizons spacecraft encountering a Kuiper Belt Object, as part of a potential extended mission after the Pluto flyby. In 2014, using the Hubble Space Telescope, New Horizons science team members discovered three KBOs - all in the range of 20-55 kilometers across, and all with possible flyby dates in late 2018 or in 2019 - a billion miles beyond Pluto. Any extended mission would require NASA approval.
