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 the identification of its origin. Here, we perform a high-resolution statistical search for stable orbits and show that asteroid (514107) 2015 BZ509 has been in its current orbital state since the formation of the Solar System. This result indicates that (514107) 2015 BZ509 was captured from the…

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 $i>90^o$) state. We estimate that at any
An interstellar origin for high-inclination Centaurs
We investigate the possible origins of real high-inclination Centaurs and trans-neptunian objects using a high-resolution statistical search for stable orbits that simulates their evolution back in
No evidence for interstellar planetesimals trapped in the Solar system
In two recent papers published in MNRAS, Namouni and Morais claimed evidence for the interstellar origin of some small Solar system bodies, including: (i) objects in retrograde co-orbital motion
Identifying Interstellar Objects Trapped in the Solar System through Their Orbital Parameters
The first interstellar object, `Oumuamua, was discovered in the Solar System by Pan-STARRS in 2017, allowing for a calibration of the abundance of interstellar objects of its size and an estimation
On the dynamical origins of retrograde Jupiter Trojans and their connection to high-inclination TNOs
Over the course of the last decade, observations of highly-inclined (orbital inclination i > 60°) Trans-Neptunian Objects (TNOs) have posed an important challenge to current models of solar system
Periodic orbits of the retrograde coorbital problem
Asteroid (514107) Ka‘epaoka‘awela is the first example of an object in the 1/1 mean motion resonance with Jupiter with retrograde motion around the Sun. Its orbit was shown to be stable over the
Generation of Unbound Comets and Planets by Planetary Systems
We present a three-dimensional model of the evolution of the asteroid–cometary–planetary (ACP) component of the Solar System under the gravitational influence of Jupiter. We demonstrate the origin of

We simulate the passage through the Sun–Jupiter system of interstellar objects (ISOs) similar to 1I/‘Oumuamua or 2I/Borisov. Capture of such objects is rare and overwhelmingly from low incoming
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.
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.
Coorbital capture at arbitrary inclination
The process of capture in the coorbital region of a solar system planet is studied. Absolute capture likelihood in the 1:1 resonance is determined by randomly constructed statistical ensembles
Discovery of a New Retrograde Trans-Neptunian Object: Hint of a Common Orbital Plane for Low Semimajor Axis, High-inclination TNOs and Centaurs
Although the majority of Centaurs are thought to have originated in the scattered disk, with the high-inclination members coming from the Oort cloud, the origin of the high-inclination component of
Discovery of the First Retrograde Transneptunian Object
We report the discovery of the first transneptunian object known to be on a retrograde orbit. The discovery was made during an outer solar system survey using the Canada–France–Hawaii Telescope
The formation of the solar system
The solar system started to form about 4.56 Gyr ago and despite the long intervening time span, there still exist several clues about its formation. The three major sources for this information are
Do Centaurs preserve their source inclinations
We have numerically investigated the long-term dynamical behavior of known Centaurs. This class of objects is thought to constitute the transitional population between the Kuiper belt and the
Jupiter Trojans are thought to be survivors of a much larger population of planetesimals that existed in the planetary region when planets formed. They can provide important constraints on the mass
Capture of the Sun's Oort Cloud from Stars in Its Birth Cluster
Numerical simulations show that the Sun captured comets from other stars while it was in its birth cluster, implying that a substantial fraction of the Oort cloud comets, perhaps exceeding 90%, are from the protoplanetary disks of other stars.
