TL;DR: The OSIRIS-REx spacecraft departed for near-Earth asteroid (101955) Bennu via an United Launch Alliance Atlas V 411 evolved expendable launch vehicle at 7:05 p.m. EDT on September 8, 2016, on a seven-year journey to return samples from Bennu as discussed by the authors.

TL;DR: Spectral observations and a principal components analysis suggest that Ryugu originates from the Eulalia or Polana asteroid family in the inner main belt, possibly via more than one generation of parent bodies.

TL;DR: The Hayabusa2 mission as mentioned in this paper was the first mission to explore a C-type near-Earth asteroid (162173) Ryugu (1999 JU3) to observe and explore the 900 m-sized object, and return samples collected from the surface layer.

Debiased orbit and absolute-magnitude distributions for near-Earth objects
Mikael Granvik,Alessandro Morbidelli,Robert Jedicke,Bryce Bolin,William F. Bottke,E. C. Beshore,David Vokrouhlický,David Nesvorný,Patrick Michel +8 more
TL;DR: In this article, the authors presented a new four-dimensional model of the near-Earth objects population that describes debiased steady-state distributions of semimajor axis, eccentricity, inclination, and absolute magnitude H in the range 17.962 − 56 + 52 + 52 ( 802 − 42 + 48 × 10 3 ) NEOs with H.

Asteroid family ages
TL;DR: In this paper, a catalog of proper elements with ∼384,000 numbered asteroids and on new methods is available, including a least squares fit of the two sides of a V-shape plot in the proper semimajor axis, inverse diameter plane to determine the corresponding slopes, an advanced error model for the uncertainties of asteroid diameters, an iterative outlier rejection scheme and quality control.

Introducing the Eulalia and new Polana asteroid families: Re-assessing primitive asteroid families in the inner Main Belt
TL;DR: The Nysa-Polana complex of asteroids was studied by Cellino et al. as mentioned in this paper, who showed that its osculating eccentricity varies widely (e.g., 0.06-0.19) on short timescales and the averaged value diffuses (between e.g. 0.11−0.15) over long timescaleres.

TL;DR: Using albedos from WISE/NEOWISE to separate distinct albedo groups within the Main Belt asteroids, this paper applied the Hierarchical Clustering Method to these subpopulations and identified dynamically associated clusters of asteroids.

Retrograde spins of near-Earth asteroids from the Yarkovsky effect.
TL;DR: It is reported that the spin vectors of NEAs show a strong and statistically significant excess of retrograde rotations, quantitatively consistent with the theoretical expectations of the Yarkovsky model.

Orbital evolution of the Gefion and Adeona asteroid families: close encounters with massive asteroids and the Yarkovsky effect
TL;DR: In this article, the authors investigated the effect of close encounters on two families, Gefion and Adeona, that have high encounter probabilities with 1 Ceres, by far the largest asteroid in the main belt.

From Magnitudes to Diameters: The Albedo Distribution of Near Earth Objects and the Earth Collision Hazard
TL;DR: In this article, the albedo distribution of the objects in and near the five intermediate sources of the Near Earth Object (NEO) population is estimated. But the authors do not know a priori the distribution of main belt asteroids over the same size range as observed NEOs.
