Figure 1: Discovery images of the L5 trailing Neptune Trojan 2008 LC18, taken at the Subaru telescope on June 7, 2008 Universal Time. The Neptune Trojan is seen moving from right to left near the center of the image. Each image is separated by about one hour in time. The background stars are stationary. This image only shows about 1 percent of the area of one image from the telescope. Astronomers Scott Sheppard (Carnegie Institution, Washington, D. C.) and Chad Trujillo (Gemini Observatory, Hilo,
