Dynamics of 2023 FW14, the second L4 Mars trojan, and a physical characterization using the 10.4 m Gran Telescopio Canarias
R. de la Fuente Marcos, J. de Leon, C. de la Fuente Marcos +5
Context. Known Mars trojans could be primordial small bodies that have remained in their present-day orbits for the age of the Solar System. Their orbital distribution is strongly…
When the horseshoe fits: Characterizing 2023 FY3 with the 10.4 m Gran Telescopio Canarias and the Two-meter Twin Telescope
R. de la Fuente Marcos, C. de la Fuente Marcos, J. de León +5
Context. The Arjuna asteroid belt is loosely defined as a diverse group of small asteroids that follow dynamically cold, Earth-like orbits. Most of them are not actively engaged in…
Past the outer rim, into the unknown: structures beyond the Kuiper Cliff
C. de la Fuente Marcos, R. de la Fuente Marcos
Although the present-day orbital distribution of minor bodies that go around the Sun between the orbit of Neptune and the Kuiper Cliff is well understood, past ~50 au from the Sun,…
Borderline hyperbolic comet C/2021 O3 (PANSTARRS) was fading as it approached the Sun
M. Evangelista-Santana, M. De Prá, J. M. Carvano +13
We present an observational and numerical study of the borderline hyperbolic comet C/2021 O3 (PANSTARRS) performed during its recent passage through the inner Solar system. Our obs…
Mini-moons from horseshoes: A physical characterization of 2022 NX1 with OSIRIS at the 10.4 m Gran Telescopio Canarias
R. de la Fuente Marcos, J. de Leon, C. de la Fuente Marcos +3
Context. The near-Earth orbital space is shared by natural objects and space debris that can be temporarily captured in geocentric orbits. Short-term natural satellites are often c…
Recent arrivals to the main asteroid belt
C. de la Fuente Marcos, R. de la Fuente Marcos
The region where the main asteroid belt is now located may have started empty, to become populated early in the history of the Solar system with material scattered outward by the t…
Centaur 2013 VZ70: Debris from Saturn's irregular moon population?
C. de la Fuente Marcos, R. de la Fuente Marcos
Context. Saturn has an excess of irregular moons. This is thought to be the result of past collisional events. Debris produced during such episodes in the neighborhood of a host pl…
Activity of the Jupiter co-orbital comet P/2019~LD (ATLAS) observed with OSIRIS at the 10.4 m GTC
J. Licandro, J. de Leon, F. Moreno +8
Jupiter co-orbital comets have orbits that are not long-term stable. They may experience flybys with Jupiter close enough to trigger tidal disruptions like the one suffered by come…
Visible and near-infrared observations of interstellar comet 2I/Borisov with the 10.4-m GTC and the 3.6-m TNG telescopes
J. de León, J. Licandro, C. de la Fuente Marcos +15
In this work, we present the results of an observational study of 2I/Borisov carried out with the 10.4-m Gran Telescopio Canarias (GTC) and the 3.6-m Telescopio Nazionale Galileo (…
Flying far and fast: the distribution of distant hypervelocity star candidates from Gaia DR2 data
R. de la Fuente Marcos, C. de la Fuente Marcos
Context. Hypervelocity stars move fast enough to leave the gravitational field of their home galaxies and venture into intergalactic space. The most extreme examples known have est…
Asteroid 2014 YX49: a large transient Trojan of Uranus
C. de la Fuente Marcos, R. de la Fuente Marcos
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…
Visible spectra of (474640) 2004 VN112-2013 RF98 with OSIRIS at the 10.4 m GTC: evidence for binary dissociation near aphelion among the extreme trans-Neptunian objects
J. de León, C. de la Fuente Marcos, R. de la Fuente Marcos
The existence of significant anisotropies in the distributions of the directions of perihelia and orbital poles of the known extreme trans-Neptunian objects (ETNOs) has been used t…
Homing in for New Year: impact parameters and pre-impact orbital evolution of meteoroid 2014 AA
C. de la Fuente Marcos, R. de la Fuente Marcos, P. Mialle
On 2008 October 7, small asteroid 2008 TC3 turned itself into the parent body of the first meteor ever to be predicted before entering the Earth's atmosphere. Over five years later…
Asteroid (469219) 2016 HO3, the smallest and closest Earth quasi-satellite
C. de la Fuente Marcos, R. de la Fuente Marcos
A number of Earth co-orbital asteroids experience repeated transitions between the quasi-satellite and horseshoe dynamical states. Asteroids 2001 GO2, 2002 AA29, 2003 YN107 and 201…
The analemma criterion: accidental quasi-satellites are indeed true quasi-satellites
C. de la Fuente Marcos, R. de la Fuente Marcos
In the Solar system, a quasi-satellite is an object that follows a heliocentric path with an orbital period that matches almost exactly with that of a host body (planetary or not).…
Finding Planet Nine: apsidal anti-alignment Monte Carlo results
C. de la Fuente Marcos, R. de la Fuente Marcos
The distribution of the orbital elements of the known extreme trans-Neptunian objects or ETNOs has been found to be statistically incompatible with that of an unperturbed asteroid…
Far from random: dynamical groupings among the NEO population
C. de la Fuente Marcos, R. de la Fuente Marcos
Among the near-Earth object (NEO) population there are comets and active asteroids which are sources of fragments that initially move together; in addition, some NEOs follow orbits…
From horseshoe to quasi-satellite and back again: the curious dynamics of Earth co-orbital asteroid 2015 SO2
C. de la Fuente Marcos, R. de la Fuente Marcos
Earth co-orbitals of the horseshoe type are interesting objects to study for practical reasons. They are relatively easy to access from our planet and that makes them attractive ta…
Chasing the Chelyabinsk asteroid N-body style
C. de la Fuente Marcos, R. de la Fuente Marcos, S. J. Aarseth
On 2013 February 15 a small asteroid rammed against the atmosphere above the region of Chelyabinsk in Russia, producing the most powerful superbolide since the Tunguska event in 19…
On the angular distribution of IceCube high-energy events
R. de la Fuente Marcos, C. de la Fuente Marcos
The detection of high-energy astrophysical neutrinos of extraterrestrial origin by the IceCube neutrino observatory in Antarctica has opened a unique window to the cosmos that may…
Asteroid 2015 DB216: a recurring co-orbital companion to Uranus
C. de la Fuente Marcos, R. de la Fuente Marcos
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…

Infrequent visitors of the Kozai kind: the dynamical lives of 2012 FC71, 2014 EK24, 2014 QD364, and 2014 UR
C. de la Fuente Marcos, R. de la Fuente Marcos
Context. Asteroids with semi-major axes very close to that of a host planet can avoid node crossings when their nodal points are at perihelion and at aphelion. This layout protects…
Flipping minor bodies: what comet 96P/Machholz 1 can tell us about the orbital evolution of extreme trans-Neptunian objects and the production of near-Earth objects on retrograde orbits
C. de la Fuente Marcos, R. de la Fuente Marcos, S. J. Aarseth
Nearly all known extreme trans-Neptunian objects (ETNOs) have argument of perihelion close to 0 degrees. An existing observational bias strongly favours the detection of ETNOs with…
