7 years ago, on New Year's Day, Jan 1, 2019, the NASA New Horizons spacecraft flew by the most distant object ever visited by a spacecraft, the contact binary trans-Neptunian object 2014 MU6, now named Arrokoth.

Arrokoth means "sky" in the Powhatan/Algonquin language.

New Horizons also saw evidence for methanol, water ice and organic molecules on the red surface of the 35 km Kuiper Belt object.
