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

Transient Jupiter Co-orbitals from Solar System Sources

We demonstrate dynamical pathways from main-belt asteroid and Centaur orbits to those in co-orbital motion with Jupiter, including the retrograde (inclination i > 90°) state. We estimate that, at any

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

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

PRODUCTION OF NEAR-EARTH ASTEROIDS ON RETROGRADE ORBITS

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

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

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
