Crantor, a short-lived horseshoe companion to Uranus
@article{Marcos2013CrantorAS, title={Crantor, a short-lived horseshoe companion to Uranus}, author={Carlos de la Fuente Marcos and Ra{\'u}l de la Fuente Marcos}, journal={Astronomy and Astrophysics}, year={2013}, volume={551} }
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 horseshoe orbits: 83982 Crantor (2002 GO9 ) and 2000 SN331 .Aims. (83982) Crantor is currently classified in the group of the Centaurs by the MPC although the value of its orbital period is close to that of Uranus. Here we revisit the topic of the possible 1:1 commensurability of (83982) Crantor with Uranus…

Most co-orbital objects in the Solar system are thought to follow tadpole-type orbits, behaving as Trojans. However, most of Earth's identified co-orbitals are moving along horseshoe-type orbits. The…
A Uranian Trojan and the Frequency of Temporary Giant-Planet Co-Orbitals
- Geology, PhysicsScience
- 2013
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.
