486958 Arrokoth

486958 Arrokoth,[lower-alpha 1] provisional designation 2014 MU₆₉, is a trans-Neptunian object located in the Kuiper belt. It is a contact binary 36 km (22 mi) long, made of two planetesimals 21 km (13 mi) and 15 km (9 mi) across, nicknamed "Ultima" and "Thule". The New Horizons team use this classical pronunciation, the pseudo-Latin pronunciation /ˈtuːleɪ/ TOO-lay, and the hybrid pronunciation /ˈtuːliː/ TOO-lee.[1][2] The surface is made of pale red tholins, formed due to the surface being exposed to UV light.[3]
