469219 Kamo`oalewa           Discovered 2016 Apr. 27 by Pan-STARRS 1 at Haleakala.
Kamo`oalewa alludes to a celestial object that is oscillating, like its path in the sky as viewed from the Earth. It is a name found in the Hawaiian chant Kumulipo. He `\=apana h\={o}k\={u}na`i i lele mai kona kino nui, he holo p\={u} me ka honua a puni ka l\=a. Name conceived by A Hua He Inoa, `Imiloa Astronomy Center of Hawai`i.
