(528219) 2008 KV42

(528219) 2008 KV42 (provisionally designated 2008 KV42, and nicknamed Drac) is a trans-Neptunian object (TNO) and the first one with a retrograde orbit to be discovered. This retrograde motion with an orbital inclination of 103° suggests that it is the missing link between its source in the Hills cloud and Halley-type comets, thus providing further insight into the evolution of the outer Solar System. The object measures no more than 90 kilometers (56 miles) across. With a semi-major axis of 42 AU, it takes about 269 years to complete an orbit around the Sun.
