Illustration of the New Horizons Kuiper belt target survey's beam through the plane of the solar system, targeting distant, encounterable Kuiper Belt Objects. This targeting coincidentally passes right through Neptune's trailing L5 Trojan cloud. White points indicate objects discovered by survey as of April 2013. Also illustrated are the Pluto system, New Horizons, and 2008 LC18 (the only other known stable L5 Neptune Trojan).
