Asteroid (101955) Bennu's weak boulders and thermally anomalous equator
Ben Rozitis,Andrew Ryan,Josh Emery,P. R. Christensen,V. E. Hamilton,Amy Simon,D. C. Reuter,M. Al Asad,Ronald-Louis Ballouz,Joshua L. Bandfield,Olivier S. Barnouin,Carina Bennett,Marc Bernacki,K. N.

Lim,Jamie Molaro,D. Pino Muñoz,Michael C. Nolan,Bashar Rizk,Matthew A. Siegler,Hannah C.M. Susorney,Kevin J. Walsh,Dante S. Lauretta +34 more
TL;DR: These findings imply that other C-complex NEAs likely have boulders similar to those on Bennu rather than finer-particulate regoliths, and a tentative correlation between albedo and thermal inertia of C- complex NEAs may be due to relative abundances of boulder types.

TL;DR: Maps of color and albedo on asteroid Bennu indicate complex evolution of its surface due to space weathering, and constrain Bennu's evolution and provide context for the sample collected in October 2020.

TL;DR: In this article, the presence of metre-scale exogenic boulders on the surface of near-Earth asteroid (101955) Bennu has been reported, which provides previously unrecognized constraints on the collisional and dynamical evolution of the inner main belt.

TL;DR: Rozitis et al. as mentioned in this paper investigated a plausible explanation that positive spectral slopes indicate a finer grain size for the most directly observed sub-Earth region on the asteroid Bennu.

Rapid planetesimal formation in turbulent circumstellar disks
Anders Johansen,Jeffrey S. Oishi,Jeffrey S. Oishi,Mordecai-Mark Mac Low,Mordecai-Mark Mac Low,Hubert Klahr,Thomas Henning,Andrew N. Youdin +7 more
TL;DR: It is reported that boulders can undergo efficient gravitational collapse in locally overdense regions in the midplane of the disk, and it is found that gravitationally bound clusters form with masses comparable to dwarf planets and containing a distribution of boulder sizes.

A low mass for Mars from Jupiter's early gas―driven migration
Kevin J. Walsh,Alessandro Morbidelli,Sean N. Raymond,Sean N. Raymond,David P. O'Brien,Avi Mandell +5 more
TL;DR: Simulation of the early Solar System shows how the inward migration of Jupiter to 1.5 au, and its subsequent outward migration, lead to a planetesimal disk truncated at 1’au; the terrestrial planets then form from this disk over the next 30–50 million years, with an Earth/Mars mass ratio consistent with observations.

The Long-Term Dynamical Behavior of Short-Period Comets
TL;DR: In this paper, the authors developed and tested a new computer code to follow the long-term dynamical evolution of a swarm of test particles in the solar system and found that the Tisserand parameter, T, does not vary substantially for most comets.

Debiased Orbital and Absolute Magnitude Distribution of the Near-Earth Objects
William F. Bottke,Alessandro Morbidelli,Robert Jedicke,Jean-Marc Petit,Harold F. Levison,Patrick Michel,Travis S. Metcalfe +6 more
TL;DR: In this article, a best-fit model of the near-Earth objects (NEOs) population is presented, which is fit to known NEs discovered or accidentally rediscovered by Spacewatch.
The long-term dynamical behavior of short-period comets
TL;DR: In this article, it is shown that the anomalous concentration of the argument of perihelion of the Jupiter-family comets near 0 and 180 deg is a direct result of their aphelion distance being close to 5.2AU and the comet being recently perturbed onto a Jupiter- family orbit.
