Quick Summary

2014 MU69, now known as Arrokoth, is a Kuiper Belt object that the New Horizons space probe flew by on January 1, 2019. The Kuiper Belt is a region beyond Neptune containing small celestial bodies, from which many short-period comets are thought to originate. Arrokoth was discovered to be a contact binary, meaning it is composed of two objects that merged together.12
