Apart from Mercury that has no known co-orbital companions, Venus remains as the inner planet that hosts the smallest number of known co-orbitals (two): (322756) 2001 CK 32 and 2002 VE 68 . Both objects have absolute magnitudes 18 < H < 21 and were identified as Venus co-orbitals in 2004. Here, we analyse the orbit of the recently discovered asteroid 2012 XE 133 with H = 23.5 mag to conclude that it is a new Venus co-orbital currently following a transitional trajectory between Venus…

Asteroid 2013 ND15: Trojan companion to Venus, PHA to the Earth
Venus has three known co-orbitals: (322756) 2001 CK32, 2002 VE68 and 2012 XE133. The first two have absolute magnitudes 18 < H < 21. The third one, significantly smaller at H = 23.4 mag, is a recent…
A Deep Search for Stable Venus Co-orbital Asteroids: Limits on the Population
A stable population of objects co-orbiting with Venus was recently hypothesized in order to explain the existence of Venus’s co-orbital dust ring. We conducted a five days twilight survey for these…
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…
Threat from Within: Excitation of Venus’s Co-orbital Asteroids to Earth-crossing Orbits
All five currently known asteroids in the 1:1 mean-motion resonance (co-orbital) with Venus cross Earth’s orbit. We explore a scenario in which these near-Earth asteroids originate in a reservoir of…
Asteroid 2014 OL339: yet another Earth quasi-satellite
Our planet has one permanently bound satellite -the Moon-, a likely large number of mini-moons or transient irregular natural satellites, and three temporary natural retrograde satellites or…
Understanding the evolution of Atira-class asteroid 2019 AQ3, a major step towards the future discovery of the Vatira population
Orbiting the Sun at an average distance of 0.59 au and with the shortest aphelion of any known minor body, at 0.77 au, the Atira-class asteroid 2019 AQ3 may be an orbital outlier or perhaps an…
A Uranian Trojan and the Frequency of Temporary Giant-Planet Co-Orbitals
TLDR
The detection of a Uranian Trojan is reported and a Centaur model is constructed, supplied from the transneptunian region, to estimate temporary co-orbital capture frequency and duration, finding that at any time 0.4 and 2.8% of the population will be Uranian and Neptunian co-orbitals, respectively.
Transient Co-orbitals of Venus: An Update
Venus has no known satellites, but has four known co-orbitals: (322756) 2001 CK32, 2002 VE68, 2012 XE133, and 2013 ND15. Here, we present numerical evidence suggesting that 2015 WZ12 is a possible…
Observational signatures of SNIa progenitors, as predicted by models
A definitive determination of the progenitors of type Ia supernovae (SNIa) has been a conundrum for decades. The single degenerate scenario $-$ a white dwarf (WD) in a semi-detached binary system…

Asteroid 2002 VE68, a quasi-satellite of Venus
The asteroid 2002 VE68 is currently a quasi-satellite of Venus, the first object of this dynamical class to be discovered, and is also the first known co-orbital companion to Venus. Our computations…
On the dynamical evolution of 2002 VE68
The minor planet 2002 VE68 was identified as a quasi-satellite of Venus shortly after its discovery. At that time its data-arc span was only 24 d; now it is 2947 d. Here we revisit the topic of the…

A Numerical Survey of Transient Co-orbitals of the Terrestrial Planets
Abstract We have investigated numerically the evolution of near-Earth asteroids (3753) Cruithne, (3362) Khufu, 1989 VA, (10563) 1993 WD, and 1994 TF2 that enter the coorbital regions of the Earth or…

The Orbital Evolution of Near-Earth Asteroid 3753
Asteroid 3753 (1986 TO) is in a 1:1 mean motion resonance with Earth, on a complex horseshoe-type orbit. Numerical experiments are performed to determine its medium-term stability and the means by…
Debiased Orbital and Absolute Magnitude Distribution of the Near-Earth Objects
The orbital and absolute magnitude distribution of the near-Earth objects (NEOs) is difficult to compute, partly because only a modest fraction of the entire NEO population has been discovered so…
Long-term stability of horseshoe orbits
Unlike Trojans, horseshoe coorbitals are not generally considered to be long-term stable (Dermott & Murray 1981a; Murray & Dermott 1999). As the lifetime of Earth’s and Venus’s horseshoe coorbitals…
Understanding the distribution of near-earth asteroids
We have deduced the orbital and size distributions of the near-Earth asteroids (NEAs) by (i) numerically integrating NEAs from their source regions to their observed orbits, (ii) estimating the…
Secular Interactions of Coorbiting Objects
Abstract We study the dynamics of the three-body problem when two objects are in the 1:1 mean motion commensurability and can experience close encounters. Three orbit families are relevant to the…
