Small but mighty: Impact hazards from iron Near‐Earth Objects

Meteoritics &Planetary Science, EarlyView.
Abstract Small asteroids can impact Earth unexpectedly, as demonstrated by the Chelyabinsk event in 2013. The warning times are likely to be short, and the first tools for fast hazard predictions have been developed in the last years for encounters with rocky or cometary objects, which quickly fragment in the atmosphere and cause airbursts. However, in

Asteroid taxonomic signatures from photometric phase curves

, 2012
We explore the correlation between an asteroid's taxonomy and photometric phase curve using the H, G12 photometric phase function, with the shape of the phase function described by the single parameter G12.

Rapid terrestrial weathering of the CI1 carbonaceous chondrite find Oued Chebeika 002

Meteoritics &Planetary Science, EarlyView.
Abstract Alteration of historic CI1 meteorite falls during their curation demonstrates the susceptibility of smectite‐rich carbonaceous chondrites to terrestrial exposure. The discovery of Oued Chebeika 002 in Morocco in June 2024 presents a unique opportunity to document the earliest stages of weathering of a CI1 find.

Asteroid Collisions: Expected Visibility and Rate

The Astronomical Journal
Asteroid collisions are one of the main processes responsible for the evolution of bodies in the main belt. Using observations of the Dimorphos impact by the DART spacecraft, we estimate how asteroid collisions in the main belt may look in the first ...

Disintegration and Skipping Dynamics of Bilobate‐Shaped Meteoroids for Generating Ultra‐Long Strewn Fields

Earth and Space Science, Volume 13, Issue 2, February 2026.
Abstract The longest known Aletai meteorite belt presents a unique phenomenon in meteoroid dynamics. To investigate its formation mechanism, this study introduces a bilobate‐shaped meteoroid model, emphasizing aerodynamic interactions and structure evolution.

Evidence for a colour dependence in the size distribution of main belt asteroids [PDF]

, 2006
We present the results of a project to detect small (~1 km) main-belt asteroids with the 3.6 meter Canada-France-Hawaii Telescope (CFHT). We observed in 2 filters (MegaPrime g' and r') in order to compare the results in each band.

Formation of Asteroid (16) Psyche by a Giant Impact

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Asteroid (16) Psyche is the largest likely metal‐rich asteroid in the Solar System and the target of the NASA Psyche mission. The mission aims to determine whether the asteroid is the core of a differentiated planetesimal that lost its mantle via a giant impact.

Mean Motion Resonances in the Asteroid Belt [PDF]

International Astronomical Union Colloquium, 1999
The Kirkwood gaps in the main asteroidal belt (2 – 3.5 AU) coincide with the mean motion resonances with Jupiter (4/1, 3/1, 5/2, 7/3, 2/1). Similarly, several narrower gaps are observed in the outer asteroid belt (3.5 – 4 AU) at places of 11/6, 9/5, 7/4 and 5/3 Jovian resonances (Holman and Murray 1996).

The Network State, Exit, and the Political Economy of Venture Capital

Antipode, Volume 58, Issue 1, January 2026.
Abstract This article focuses on the Network State movement as embodying the venture capital (VC) logic of exit. Exit constitutes both a strategy for lucrative returns and an ideology seeking out new territories for financial and technological speculation.
