(120216) 2004 EW95 (provisional designation 2004 EW95) is a resonant trans-Neptunian object in the Kuiper belt located in the outermost regions of the Solar System. It measures approximately 291 kilometers in diameter.[7] It has more carbon than typical of KBOs, and the first to be confirmed as having this composition in this region of space.[8] It is thought to have originated closer to the Sun, perhaps even in the main asteroid belt.[8]
