Most distant world ever explored gets new name: Arrokoth
Object beyond Pluto had been called Ultima Thule, but nickname was controversial due to Nazi links
The most distant world ever explored 6.4 billion kilometres away finally has an official name: Arrokoth.
That means "sky" in the language of the Native American Powhatan people, NASA said Tuesday.
NASA's New Horizons spacecraft flew past the snowman-shaped Arrokoth on New Year's Day, 3 ½ years after exploring Pluto. At the time, this small icy world 1.6 billion kilometres beyond Pluto was nicknamed Ultima Thule, the term used in medieval maps and literature in reference to the farthest place beyond the borders of the known world. But the nickname was controversial because it had also been used by the Nazis as the mythological homeland of the "Aryan race."
"The name 'Arrokoth' reflects the inspiration of looking to the skies," lead scientist Alan Stern of Southwest Research Institute said in a statement, "and wondering about the stars and worlds beyond our own."
'Arrokoth': a Native American term meaning “sky” in the Powhatan/Algonquian language. With consent from Powhatan Tribal elders and representatives, it's now the official name for the Kuiper Belt object visited by <a href="https://twitter.com/NASANewHorizons?ref_src=twsrc%5Etfw">@NASANewHorizons</a>.

The name was picked because of the Powhatan's ties to the Chesapeake Bay region.
New Horizons is operated from Johns Hopkins University's Applied Physics Lab in Laurel, Maryland. The Hubble Space Telescope — which discovered Arrokoth in 2014 — has its science operations in Baltimore.
The New Horizons team got consent for the name from Powhatan Tribal elders and representatives, according to NASA. The International Astronomical Union and its Minor Planet Center approved the choice.
Arrokoth is among countless objects in the so-called Kuiper Belt, or vast Twilight Zone beyond the orbit of Neptune. New Horizons will observe some of these objects from afar as it makes its way deeper into space.
