Exploring the Interior Structure of (16) Psyche Through Basin‐Scale Collisions

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Asteroid (16) Psyche, the largest member of the M/X‐type asteroids, may be the leftover core of a differentiated planetesimal. As such (16) Psyche will be explored in detail by NASA's discovery‐class Psyche mission in 2029. This will be the first mission to orbit a metal‐rich asteroid, or any asteroid in the 100–500 km size range.

Modelling of asteroid formation in planetary vortex and calculation its orbital parameters

Vìsnik Dnìpropetrovsʹkogo Unìversitetu: Serìâ Modelûvannâ, 2015
The theory of planetary vortex as the initial state of creation of the star systems is used to the study of conditions of formation of asteroids and calculation its orbital parameters.

Asymmetric Crater Relaxation on an Ice‐Rich Ceres Driven by Insolation

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Ceres has a high ice content within its crust and is the closest dwarf planet to the sun. The resultant high insolation levels at Ceres' surface (in comparison to the outer solar system) leads to high variations in surface temperature, which is dependent on both latitude and orientation of the slope (i.e., equatorward‐ or poleward‐facing).

Physical characterization and origin of binary near-Earth asteroid (175706) 1996 FG3

, 2011
The near-Earth asteroid (NEA) (175706) 1996 FG3 is a particularly interesting spacecraft target: a binary asteroid with a low-DeltaV heliocentric orbit. The orbit of its satellite has provided valuable information about its mass density while its albedo ...

Al‐Khadhaf: The first camera‐observed (H5–6) meteorite fall from Oman

Meteoritics &Planetary Science, Volume 61, Issue 3, Page 522-547, March 2026.
Abstract A fireball camera system installed in 2022 by the Oman Meteorite Monitoring Project (OMMP) as part of the Global Fireball Observatory (GFO) recorded a 3.2 s fireball on March 8, 2022 at 8:15 p.m. UTC. A meteoroid of 4 ± 2 kg entered the atmosphere at 14.0 km/s.

The Solar Nebula on Fire: A Solution to the Carbon Deficit in the Inner Solar System

, 2010
Despite a surface dominated by carbon-based life, the bulk composition of the Earth is dramatically carbon poor when compared to the material available at formation.

The Link between Athor and EL Meteorites Does Not Constrain the Timing of the Giant Planet Instability

The Astrophysical Journal Letters
The asteroid Athor, residing today in the inner main asteroid belt, has been recently identified as the source of EL enstatite meteorites to Earth. It has been argued that Athor formed in the terrestrial region—as indicated by a similarity in isotopic ...

Observational Constraints on the Catastrophic Disruption Rate of Small Main Belt Asteroids

, 2014
We have calculated 90% confidence limits on the steady-state rate of catastrophic disruptions of main belt asteroids in terms of the absolute magnitude at which one catastrophic disruption occurs per year (HCL) as a function of the post-disruption ...

Considering Contact Forces during the Formation of Planetesimals by Gravitational Collapse: Mutual Orbits, Spin States, and Shapes

The Astrophysical Journal
In this work, we apply a soft-sphere discrete element method (SSDEM) within the PKDGRAV N -body integrator to investigate the formation of planetesimal systems through the gravitational collapse of clouds of superparticles. Previously published numerical
