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
- Physics, GeologyAstronomy & Astrophysics

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

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
- Physics, Geology

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
- Physics, GeologyNature
- 2017
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
- Physics, Geology
