This video shows the location of the largest Jupiter Trojan asteroid (624) Hektor. With a size of 270 km long and 200 km wide, Hektor has a bi-loped shape. in 2006, our team discovered a small 12-km moon in orbit around the primary. This moon has a unique and special orbit. It is inclined (55 deg) and strongly elliptical (e=0.3). Our study revealed that the moon is probably an ejecta produced by the low-velocity encounter that formed the bilobed primary. The asteroid itself is a complex mini-geological world, probably a primitive captured Kuiper belt object which is differentiated with a dense core of icy material. We will know more about this interesting body when we would send a spacecraft to explore this area of the Solar System.
