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… 
Survey of asteroids in retrograde mean motion resonances with planets
Aims. Asteroids in mean motion resonances (MMRs) with planets are common in the solar system. In recent years, increasingly more retrograde asteroids are discovered, several of which are identified
How long will asteroids on retrograde orbits survive
New Extreme Trans-Neptunian Objects: Towards a Super-Earth in the Outer Solar System
We are conducting a survey for extreme solar system objects to understand Sedna and 2012 VP113 and determine if an unknown massive planet exists in the outer solar system. Two new objects, 2014 SR349
Dynamical lifetimes of asteroids in retrograde orbits
The population of known minor bodies in retrograde orbits ($i > 90 ^{\circ}$) that are classified as asteroids is still growing. The aim of our study was to estimate the dynamical lifetimes of these
Flipping minor bodies: what comet 96P/Machholz 1 can tell us about the orbital evolution of extreme trans-Neptunian objects and the production of near-Earth objects on retrograde orbits
Nearly all known extreme trans-Neptunian objects (ETNOs) have argument of perihelion close to 0 degrees. An existing observational bias strongly favours the detection of ETNOs with arguments of
The Dynamical History Of 2060 Chiron And Its Proposed Ring System
The surprising discovery of a ring system around the Centaur 10199 Chariklo in 2013 led to a reanalysis of archival stellar occultation data for the Centaur 2060 Chiron by Ortiz et al. One possible
Flip mechanism of Jupiter-crossing orbits in the non-hierarchical triple system
With the discovery of more and more retrograde minor bodies, retrograde orbits’ production mechanism has attracted much attention. However, almost all of the current research on the flip mechanism

The case for implementation of moving target tracking is presented, a feature that will benefit from the heritage of JWST and enable a broader range of solar system observations.


Asteroids in retrograde resonance with Jupiter and Saturn
ABSTRACT We identify a set of asteroids among Centaurs and Damocloids, that orbit contrary to thecommon direction of motion in the Solar System and that enter into resonance with Jupiterand Saturn.
Crantor, a short-lived horseshoe companion to Uranus
Context. Stable co-orbital motion with Uranus is vulnerable to planetary migration, but temporary co-orbitals may exist today. So far, only two candidates have been suggested, both moving on
Do Centaurs preserve their source inclinations
Surface composition? and dynamical evolution of two retrograde objects in the outer solar system: 2008 YB3 and 2005 VD
Most of the objects in the trans-Neptunian belt (TNb) and related populations move in prograde orbits with low eccentricity and inclination. However, the list of icy minor bodies moving in orbits
Simulations of the population of Centaurs – I. The bulk statistics
Large-scale simulations of the Centaur population are carried out. The evolution of 23 328 particles based on the orbits of 32 well-known Centaurs is followed for up to 3 Myr in the forward and
A Model for the Common Origin of Jupiter Family and Halley Type Comets
A numerical simulation of the Oort cloud is used to explain the observed orbital distributions and numbers of Jupiter-family (JF) and Halley-type (HT) short-period (SP) comets. Comets are given

High-inclination planets and asteroids in multistellar systems
The Kozai mechanism often destabilizes high-inclination orbits. It couples changes in the eccentricity and inclination, and drives high inclination, circular orbits to low inclination, eccentric

Abstract We present numerical orbital integrations of thousands of massless particles as they evolve from Neptune-encountering orbits in the Kuiper belt for up to 1 Gyr or until they either impact a
