The NEO Coordination Centre (NEOCC) of the European Space Agency is an operational centre that, among other activities, computes the orbits of near-Earth objects and their probabil…
Mining archival data from wide-field astronomical surveys in search of near-Earth objects
Teymoor Saifollahi, Gijs Verdoes Kleijn, Rees Williams +5
Increasing our knowledge of the orbits and compositions of Near-Earth Objects (NEOs) is important for a better understanding of the evolution of the Solar System and of life. The d…
Observational Characterization of Main-Belt Comet and Candidate Main-Belt Comet Nuclei
Henry H. Hsieh, Marco Micheli, Michael S. P. Kelley +9
We report observations of nine MBCs or candidate MBCs, most of which were obtained when the targets were apparently inactive. We find effective nucleus radii (assuming albedos of p…
Asteroids seen by JWST-MIRI: Radiometric Size, Distance and Orbit Constraints
T. G. Müller, M. Micheli, T. Santana-Ros +3
Infrared measurements of asteroids are crucial for the determination of physical and thermal properties of individual objects, and for the understanding of the small-body populatio…
(523599) 2003 RM: The asteroid that wanted to be a comet
Davide Farnocchia, Darryl Z. Seligman, Mikael Granvik +11
We report a statistically significant detection of nongravitational acceleration on the sub-kilometer near-Earth asteroid (523599) 2003 RM. Due to its orbit, 2003 RM experiences fa…
Dark Comets? Unexpectedly Large Nongravitational Accelerations on a Sample of Small Asteroids

We report statistically significant detections of non-radial nongravitational accelerations based on astrometric data in the photometrically inactive objects 1998 KY, 2005 V…
TNO or Comet? The Search for Activity and Characterization of Distant Object 418993 (2009 MS9)
Erica Bufanda, Karen J. Meech, Jan T. Kleyna +10
2009 MS9 is a trans-Neptunian object (TNO) whose perihelion brings it close to the distance where some long period comets are seen to become active. Knowing this, and the fact that…
A Deep and Wide Twilight Survey for Asteroids Interior to Earth and Venus
Scott S. Sheppard, David Tholen, Petr Pokorny +17
We are conducting a survey using twilight time on the Dark Energy Camera with the Blanco 4m telescope in Chile to look for objects interior to Earth's and Venus' orbits. To date we…
Elimination of a virtual impactor of 2006 QV89 via deep non-detection
Olivier R. Hainaut, Marco Micheli, Juan Luis Cano +3
As a consequence of the large (and growing) number of near-Earth objects discovered, some of them are lost before their orbit can be firmly established to ensure long-term recovery…
The similarity of the interstellar comet 2I/Borisov to solar system comets from high resolution optical spectroscopy
C. Opitom, E. Jehin, D. Hutsemékers +11
2I/Borisov - hereafter 2I - is the first visibly active interstellar comet observed in the solar system, allowing us for the first time to sample the composition of a building bloc…
The impact and recovery of asteroid 2018 LA
Peter Jenniskens, Mohutsiwa Gabadirwe, Qing-Zhu Yin +63
The June 2, 2018, impact of asteroid 2018 LA over Botswana is only the second asteroid detected in space prior to impacting over land. Here, we report on the successful recovery of…
(6478) Gault: Physical characterization of an active main-belt asteroid
Maxime Devogèle, Marin Ferrais, Emmanuel Jehin +22
In December 2018, the main-belt asteroid (6478)~Gault was reported to display activity. Gault is an asteroid belonging to the Phocaea dynamical family and was not previously known…
Characterizing the Manx Candidate A/2018 V3
Caroline Piro, Karen J. Meech, Erica Bufanda +10
Manx objects approach the inner solar system on long-period comet (LPC) orbits with the consequent high inbound velocities, but unlike comets, Manxes display very little to no acti…
Establishing Earth's Minimoon Population through Characterization of Asteroid 2020 CD
Grigori Fedorets, Marco Micheli, Robert Jedicke +20
We report on our detailed characterization of Earth's second known temporary natural satellite, or minimoon, asteroid 2020 CD3. An artificial origin can be ruled out based on its a…
A search for the origin of the interstellar comet 2I/Borisov
Coryn A. L. Bailer-Jones, Davide Farnocchia, Quanzhi Ye +2
The discovery of the second interstellar object 2I/Borisov on 2019 August 30 raises the question of whether it was ejected recently from a nearby stellar system. Here we compute th…
Pre-discovery Activity of New Interstellar Comet 2I/Borisov Beyond 5 AU
Quanzhi Ye, Michael S. P. Kelley, Bryce T. Bolin +15
Comet 2I/Borisov, the first unambiguous interstellar comet ever found, was discovered in August 2019 at au from the Sun on its inbound leg. No pre-discovery detection beyon…
2I/Borisov: A C depleted interstellar comet
C. Opitom, A. Fitzsimmons, E. Jehin +9
The discovery of the first active interstellar object 2I/Borisov provides an unprecedented opportunity to study planetary formation processes in another planetary system. In partic…
