The farthest cosmic body ever visited by a spacecraft has been renamed as Arrokoth. The earlier name given to it was Ultima Thule, which meant the extreme limit of travel and discovery. The name however received a backlash because of its connections to the Nazi party. The new name comes from the native American Powhattan language and mean the Sky. Arrokth is in the frigid Kuiper belt a billion miles from Pluto. It was surveyed by NASA’s spaceship the New Horizon. It is a cold classical object which has not been disturbed for the last 4.5 billion years.
