Large retrograde Centaurs: visitors from the Oort cloud?
@article{Marcos2014LargeRC, title={Large retrograde Centaurs: visitors from the Oort cloud?}, author={Carlos de la Fuente Marcos and Ra{\'u}l de la Fuente Marcos}, journal={Astrophysics and Space Science}, year={2014}, volume={352}, pages={409-419} }
Among all the asteroid dynamical groups, Centaurs have the highest fraction of objects moving in retrograde orbits. The distribution in absolute magnitude, H, of known retrograde Centaurs with semi-major axes in the range 6–34 AU exhibits a remarkable trend: 10 % have H 12 mag. The largest objects, namely (342842) 2008 YB3, 2011 MM4 and 2013 LU28, move in almost polar, very eccentric paths; their nodal points are currently located near perihelion and aphelion. In the group of retrograde…
