2008 KV42
(nicknamed ''Drac'') is the first trans-Neptunian object (TNO) with a retrograde orbit to be discovered. Its 104° inclination and its retrograde motion suggest that it is the missing link between its source in the inner Oort cloud and Halley-type comets, thus providing further insight into the evolution of the outer Solar System. The object measures no more than 90 km across and with a semi-major axis of 45.462 AU takes a little over 306 years to complete an orbit around the Sun.
The discovery of the object was announced on July 16, 2008, by the Canada France Ecliptic Plane Survey team led by Brett Gladman. An official name has yet to be chosen by the International Astronomical Union (IAU); the discovery team nicknamed it 2008 KV42 "Drac" after Count Dracula.
== Discovery and naming ==
The discovery of 2008 KV42 was announced on July 16, 2008 by the Canada France Ecliptic Plane Survey team led by Brett Gladman from the University of British Columbia.〔 The announcement was made during the "Asteroids, Comets, Meteors" meeting held in Baltimore, Maryland, followed by a Minor Planet Electronic Circular on the same day and a IAU Circular on July 18. The discovery was made using images obtained on May 31 from the 3.5 meter Canada-France-Hawaii Telescope, followed by further observations until July 8 from the Whipple Observatory and Cerro Tololo.
The discovery team nicknamed 2008 KV42 ''Drac'' because of its high inclination in reference to the orbital plane which resembles Count Dracula's ability to walk on walls.
