ARROKOTH

Nov. 16, 2019

In a fitting tribute to the farthest flyby ever conducted by spacecraft, the Kuiper Belt object 2014 MU69 has been officially named Arrokoth, a Native American term meaning “sky” in the Powhatan/Algonquian language.

About:

  • About 6.6 billion km from Earth in the Kuiper Belt beyond the orbit of Neptune, a rock moves in slow orbit around the Sun, once every 297 years. Its odd shape consists of two lobes, respectively measuring 21 km and 15 km across, which create an appearance of a doughnut.

  • Provisionally named 2014 MU69 based on the year of its discovery, it was given the nickname ‘Ultima Thule’ last year following public suggestions made to NASA.

  • Now, it has got an official name — Arrokoth. Arrokoth is the term for “sky” in the Native American languages Powhatan and Algonquian.

  • NASA proposed the name to the International Astronomical Union and Minor Planets Centre, the authority responsible for naming objects that lie in the Kuiper Belt. The Belt consists of a mass of icy objects that include Pluto, the dwarf planet.
