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. Their orbits have inclinations I & 140  and semi-major axes a < 15 AU. Twoobjects are currently in retrograde resonance with Jupiter: 2006 BZ8 in the 2/-5 resonance and2008 SO218 in the 1/-2 resonance. One object, 2009 QY6, is currently in the 2/-3 retrograderesonance with Saturn. These are the first…

Centaurs potentially in retrograde co-orbit resonance with Saturn
Aims. The asteroid 2015 BZ509 is the first asteroid confirmed to be in retrograde co-orbit resonance (or 1/−1 resonance) with the giant planets in the solar system. While Saturn is the only giant
A retrograde object near Jupiter's orbit
Abstract Asteroid 2007 VW266 is among the rare objects with a heliocentric retrograde orbit, and its semimajor axis is within a Hill sphere radius of that of Jupiter. This raised the interesting
Large retrograde Centaurs: visitors from the Oort cloud?
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
Resonances in the asteroid and trans–Neptunian belts: A brief review
Abstract Mean motion resonances play a fundamental role in the dynamics of the small bodies of the Solar System. The last decades of the 20th century gave us a detailed description of the dynamics as
Planetary science: Reckless orbiting in the Solar System
Additional observations are presented and analysed to confirm that 2015 BZ509 is circling the Sun in a clockwise (retrograde) direction, when looking down on the Solar System, in the region of Jupiter, which is orbiting anticlockwise (prograde motion).
An interstellar origin for Jupiter’s retrograde co-orbital asteroid
Asteroid (514107) 2015 BZ509 was discovered recently in Jupiter's co-orbital region with a retrograde motion around the Sun. The known chaotic dynamics of the outer Solar System have so far precluded
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
A retrograde co-orbital asteroid of Jupiter
Observations and analysis demonstrate that asteroid 2015 BZ509 is indeed a retrograde co-orbital asteroid of the planet Jupiter and has long-term stability, having been in its current, resonant state for around a million years.
First trans-Neptunian object in polar resonance with Neptune
Capture in mean motion resonance has been observed in the Solar System for small objects with prograde as well as retrograde orbits of moderate inclinations. However, no example of an object with a
Dynamic Portrait of the Retrograde 1:1 Mean Motion Resonance
Asteroids in mean motion resonances with giant planets are common in the solar system, but it was not until recently that several asteroids in retrograde mean motion resonances with Jupiter and


While computing an improved near-Earth object (NEO) steady-state orbital distribution model, we discovered in the numerical integrations the unexpected production of retrograde orbits for asteroids
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
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
On the Asteroidal Population of the First-Order Jovian Resonances
Abstract The frequency map analysis was applied to the fairly realistic models of the 2/1, 3/2, and 4/3 jovian resonances and the results were compared with the asteroidal distribution at these
The Resonant Structure of the Kuiper Belt and the Dynamics of the First Five Trans-Neptunian Objects
Abstract By means of simple analytic models and numerical integrations, we explore the resonant structure of the Kuiper belt. We find that the inner order-one mean motion resonances with Neptune are
Meteorites may follow a chaotic route to Earth
It is widely believed that meteorites originate in the asteroid belt, but the precise dynamical mechanism whereby material is transported to Earth has eluded discovery. The observational data for the
The Phase Space Structure Near Neptune Resonances in the Kuiper Belt
The Solar system beyond Neptune is believed to house a population of small primordial bodies left over from the planet formation process. The region up to heliocentric distance -50 AU (a.k.a. the
A First Look at the Damocloids
The Damocloids are objects thought, on dynamical grounds, to be inactive Halley-family and long-period comets. We present optical measurements of 12 such objects, finding that their mean Kron-Cousins
Do Centaurs preserve their source inclinations
Abstract The Centaurs are a population of small, planet-crossing objects in the outer Solar System. They are dynamically short-lived and represent the transition population between the Kuiper belt
On The Origin of The High-Perihelion Scattered Disk: The Role of The Kozai Mechanism And Mean Motion Resonances
AbstractWe study the transfer process from the scattered disk (SD) to the high-perihelion scattered disk (HPSD) (defined as the population with perihelion distances q > 40 AU and semimajor axes a>50
