541132 Lele\=ak\={u}honua           Discovered 2015 Oct. 13 by D. J. Tholen, C. A. Trujillo and S. S. Sheppard at Mauna Kea.
Lele\=ak\={u}honua is a life form mentioned in the Hawaiian creation chant, the Kumulipo. The name compares the orbit to the flight of migratory birds and evokes a yearning to be near Earth. Me he manu i ke ala p\={o}`aiapuni l\=a, he pa`a mau n\={o} ia i ka hui me kona p\={u}nana i kumu mai ai.
