Large main-belt asteroids with visible geometric albedos below 0.1 are predominantly classified within the C- and X-complex spectroscopic classes. C-type and dark X-type asteroids…
Different arrival times of CM and CI-like bodies from the outer Solar System to the asteroid belt
Sarah E. Anderson, Pierre Vernazza, Miroslav Brož
Understanding the provenance of CI and CM chondrites, the most primitive materials in our meteorite collections, is critical for shedding light on the Solar System's early evolutio…
Understanding the formation of Saturn's regular moons in the context of giant planet moons formation scenarios
Michel Blanc, Aurélien Crida, Yuhito Shibaike +7
This article explores the different formation scenarios of the Kronian moons system in the context of a highly dissipative Saturn, with the objective of identifying the most likely…
Triton and Pluto: same origin but separated at birth
Olivier Mousis, Sarah E. Anderson, Adrienn Luspay-Kuti +2
Assessing the origin of Pluto and Triton has profound implications for the bigger picture of Solar System formation and evolution. In such a context, this chapter reviews our curre…
Young asteroid families as the primary source of meteorites
M. Brož, P. Vernazza, M. Marsset +4
Understanding the origin of bright shooting stars and their meteorite samples is among the most ancient astronomy-related questions that at larger scales has human consequences [1-…
Current status of the Extension of the FRIPON network in Chile

Planetary Exploration Horizon 2061 Report, Chapter 3: From science questions to Solar System exploration
Véronique Dehant, Michel Blanc, Steve Mackwell +31
This chapter of the Planetary Exploration Horizon 2061 Report reviews the way the six key questions about planetary systems, from their origins to the way they work and their habit…
Spectral evolution of dark asteroid surfaces induced by space weathering over a decade
Sunao Hasegawa, Francesca E. DeMeo, Michael Marsset +20
The surface of airless bodies like asteroids in the Solar System are known to be affected by space weathering. Experiments simulating space weathering are essential for studying th…
Connecting Asteroids and Meteorites with visible and near-infrared spectroscopy
Francesca E. DeMeo, Brian J. Burt, Michaël Marsset +12
We identify spectral similarities between asteroids and meteorites. We identify spectral matches between 500 asteroid spectra and over 1,000 samples of RELAB meteorite spectra over…
The debiased compositional distribution of MITHNEOS: Global match between the near-Earth and main-belt asteroid populations and excess of D-type Near-Earth Objects
Michaël Marsset, Francesca E. DeMeo, Brian Burt +10
We report 491 new near-infrared spectroscopic measurements of 420 near-Earth objects (NEOs) collected on the NASA InfraRed Telescope Facility (IRTF) as part of the MIT-Hawaii NEO S…
The appearance of a 'fresh' surface on 596 Scheila as a consequence of the 2010 impact event
Sunao Hasegawa, Michael Marsset, Francesca E. DeMeo +8
Dust emission was detected on main-belt asteroid 596 Scheila in December 2010, and attributed to the collision of a few-tens-of-meters projectile on the surface of the asteroid. In…
Observed tidal evolution of Kleopatra's outer satellite
M. Brož, J. Ďurech, B. Carry +8
The orbit of the outer satellite Alexhelios of (216) Kleopatra is already constrained by adaptive-optics astrometry, obtained with the VLT/SPHERE instrument. However, there is also…
(216) Kleopatra, a low density critically rotating M-type asteroid
F. Marchis, L. Jorda, P. Vernazza +36
Context. The recent estimates of the 3D shape of the M/Xe-type triple asteroid system (216) Kleopatra indicated a density of 5 g.cm. Such a high density implies a high metal…
Discovery of two TNO-like bodies in the asteroid belt
Sunao Hasegawa, Michael Marsset, Francesca E. DeMeo +6
Two extremely red main-belt asteroids: 203 Pompeja and 269 Justitia, were identified from combined visible and near-infrared spectroscopic observations collected at the IRTF and SA…
An advanced multipole model for (216) Kleopatra triple system
M. Brož, F. Marchis, L. Jorda +37
To interpret adaptive-optics observations of (216) Kleopatra, we need to describe an evolution of multiple moons, orbiting an extremely irregular body and including their mutual in…
Evidence for differentiation of the most primitive small bodies
B. Carry, P. Vernazza, F. Vachier +40
Dynamical models of Solar System evolution have suggested that P-/D-type volatile-rich asteroids formed in the outer Solar System and may be genetically related to the Jupiter Troj…
