An ancient L- type family associated to (460) Scania in the Middle Main Belt as revealed by Gaia DR3 spectra
Roberto Balossi, Paolo Tanga, Marco Delbo +2
Asteroid families are typically identified using hierarchical clustering methods (HCM) in the proper element phase space. However, these methods struggle with overlapping families,…

Binary asteroid candidates in Gaia DR3 astrometry
Luana Liberato, Paolo Tanga, David Mary +7
Asteroids with companions constitute an excellent sample for studying the collisional and dynamical evolution of minor planets. The currently known binary population were discovere…
Data Release 3: the Solar System survey

The third data release by the Gaia mission of the European Space (DR3) is the first release to provide the community with a large sample of observations for more than 150 thousand…
Asteroid Families: properties, recent advances and future opportunities
Bojan Novakovic, David Vokrouhlicky, Federica Spoto +1
Collisions are one of the key processes shaping planetary systems. Asteroid families are outcomes of such collisions still identifiable across our solar system. The families provid…
Asteroid astrometry by stellar occultations: Accuracy of the existing sample from orbital fitting
João F. Ferreira, Paolo Tanga, Federica Spoto +2
Context: Stellar occultations, greatly enhanced by the publication of the Gaia data releases, permit not only the determination of asteroid size and shape, but also the retrieval o…
Gaia Early Data Release 3: Structure and properties of the Magellanic Clouds
Gaia Collaboration, X. Luri, L. Chemin +417
We compare the Gaia DR2 and Gaia EDR3 performances in the study of the Magellanic Clouds and show the clear improvements in precision and accuracy in the new release. We also show…
Gaia Early Data Release 3: Acceleration of the solar system from Gaia astrometry
Gaia Collaboration, S. A. Klioner, F. Mignard +414
Context. Gaia Early Data Release 3 (Gaia EDR3) provides accurate astrometry for about 1.6 million compact (QSO-like) extragalactic sources, 1.2 million of which have the best-quali…
Potential asteroid discoveries by the ESA Gaia mission: Results from follow-up observations
B. Carry, W. Thuillot, F. Spoto +42
Since July 2014, the ESA Gaia mission has been surveying the entire sky down to magnitude 20.7 in the visible. In addition to the millions of stars, thousands of Solar System Objec…
Yarkovsky effect detection and updated impact hazard assessment for Near-Earth Asteroid (410777) 2009 FD
Alessio Del Vigna, Javier Roa, Davide Farnocchia +5
Near-Earth asteroid (410777) 2009 FD is a potentially hazardous asteroid with potential impacts on Earth at the end of the 22nd century. The astrometry collected during the 2019 ap…
Asteroid cratering families: recognition and collisional interpretation
Andrea Milani, Zoran Knežević, Federica Spoto +1
We continue our investigation of the bulk properties of asteroid dynamical families identified using only asteroid proper elements (Milani et al. 2014) to provide plausible collisi…
Simultaneous LSST and Euclid observations - advantages for Solar System Objects
C. Snodgrass, B. Carry, J. Berthier +17
The ESA Euclid mission is a space telescope that will survey ~15,000 square degrees of the sky, primarily to study the distant universe (constraining cosmological parameters throug…
Completeness of Impact Monitoring
Alessio Del Vigna, Andrea Milani, Federica Spoto +2
The completeness limit is a key quantity to measure the reliability of an impact monitoring system. It is the impact probability threshold above which every virtual impactor has to…

Gaia Collaboration, A. G. A. Brown, A. Vallenari +4
We present the second Gaia data release, Gaia DR2, consisting of astrometry, photometry, radial velocities, and information on astrophysical parameters and variability, for sources…
Detecting the Yarkovsky effect among near-Earth asteroids from astrometric data
Alessio Del Vigna, Laura Faggioli, Andrea Milani +3
We present an updated set of near-Earth asteroids with a Yarkovsky-related semimajor axis drift detected from the orbital fit to the astrometry. We find 87 reliable detections afte…
