A Uranian Trojan Bodies that share their orbit with that of a planet and that trail or lead the planet by 60° are called Trojans. Based on data from the Canada-France-Hawaii Telescope, Alexandersen et al. (p. 994) have found an object shadowing Uranus that is predicted to remain a Trojan for at least 700,000 years and to stay in co-orbital motion for around one million years before escaping. Observations with the Canada-France-Hawaii Telescope reveal a body that temporarily shares its orbit… 
Neptune Trojans: a Revisit and a New Membertwo
Systematic survey of the dynamics of Uranus Trojans
Context. The discovered Uranus Trojan (UT) 2011 QF99 and several candidate UTs have been reported to be in unstable orbits. This implies that the stability region around the triangular Lagrange
Asteroid 2015 DB216: a recurring co-orbital companion to Uranus
Minor bodies trapped in 1:1 co-orbital resonances with a host planet could be relevant to explain the origin of captured satellites. Among the giant planets, Uranus has one of the smallest known
Asteroid 2014 YX 49 : a large transient Trojan of Uranus
In the outer Solar system, primordial Trojan asteroids may have remained dynamically stable for billions of years. Several thousands of them accompany Jupiter in its journey around the Sun and a
OSSOS. XXIII. 2013 VZ70 and the Temporary Coorbitals of the Giant Planets
We present the discovery of 2013 VZ70, the first known horseshoe coorbital companion of Saturn. Observed by the Outer Solar System Origins Survey for 4.5 yr, the orbit of 2013 VZ70 is determined to
Comparative orbital evolution of transient Uranian co-orbitals: exploring the role of ephemeral multibody mean motion resonances
Uranus has three known co-orbitals: 83982 Crantor (2002 GO9), 2010 EU65 and 2011 QF99. Here, we perform a comparative analysis of the orbital evolution of these transient co-orbitals to understand
New Hamiltonian expansions adapted to the Trojan problem
A number of studies, referring to the observed Trojan asteroids of various planets in our Solar System, or to hypothetical Trojan bodies in extrasolar planetary systems, have emphasized the
Long-term Stability of Six Neptunian Trojans
This paper explores the long-term stability of six Neptunian Trojans. In contrast with other Neptunian Trojans, these objects have previously unknown lifetimes and larger orbital uncertainties due to

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
Neptune Trojans as a Test Bed for Planet Formation
The problem of accretion in the Trojan 1 : 1 resonance is akin to the standard problem of planet formation, transplanted from a star-centered disk to a disk centered on the Lagrange point. The newly
How Long-Lived Are the Hypothetical Trojan Populations of Saturn, Uranus, and Neptune?
We investigate the possibility that fractions of the primordial populations at the triangular Lagrangian points of Saturn, Uranus, and Neptune have survived to the present and form (as yet
2008 LC18: A potentially unstable Neptune Trojan
The recent discovery of the first Neptune Trojan at the planet's trailing (L5) Lagrange point, 2008 LC18, offers an opportunity to confirm the formation mechanism of a member of this important tracer
Long-term evolution of the Neptune Trojan 2001 QR322
ABSTRACT Wesimulated more than a hundred possible orbits of the Neptune Trojan 2001 QR322 forthe age of the Solar system. The orbits were generated randomly according to the probabilitydensity
(309239) 2007 RW10: a large temporary quasi-satellite of Neptune
Upon discovery, asteroid (309239) 2007 RW10 was considered a Neptune Trojan candidate. The object is currently listed by the Minor Planet Center as a Centaur but it is classified as a Scattered Disk
Earth’s Trojan asteroid
TLDR
It is established that 2010 TK7 is a Trojan companion of Earth, librating around the leading Lagrange triangular point, L4, whose orbit is stable over at least ten thousand years.
A long-lived horseshoe companion to the Earth
We present a dynamical investigation of a newly found asteroid, 2010 SO 16, and the discovery that it is a horseshoe companion of the Earth. The object's absolute magnitude (H = 20.7) makes this the
