CI chondrite Oued Chebeika 002 links asteroids Bennu and Ryugu to common parent body
Meteoritics &Planetary Science, Volume 61, Issue 5, Page 801-818, May 2026.Abstract CI chondrites are a compositionally primitive group of meteorites that have undergone extensive aqueous alteration, providing insights into the evolution of primitive planetesimals. Oued Chebeika 002 is the most pristine CI chondrite to date.

Masses of asteroids and total mass of the main asteroid belt [PDF]
Proceedings of the International Astronomical Union, 2015 AbstractAn estimation of the mass of the main asteroid belt was made on the basis of the new version of EPM2014 ephemerides of the Institute of Applied Astronomy of Russian Academy of Sciences using about 800000 positional observations of planets and spacecraft.

A Panspermia Origin for Venus Cloud Life
Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.Abstract Decades of study have hinted at the astrobiological potential of Venus's cloud layers. This potential is often cast as stemming from the idea that the Venusian surface was clement in the past. As the climate changed, life then remained in, or perhaps evolved and migrated to, the last habitable niche: the altitudes above ∼50 km with Earth‐like ...

Asteroids Fail to Retain Cometary Impact Signatures
The Planetary Science JournalA bombardment of comets is thought to have occurred in the inner solar system as a result of a dynamical instability among the giant planets after gas disk dispersal.

Erosive Hit-and-Run Impact Events: Debris Unbound
, 2015 Erosive collisions among planetary embryos in the inner solar system can lead to multiple remnant bodies, varied in mass, composition and residual velocity. Some of the smaller, unbound debris may become available to seed the main asteroid belt.

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.Abstract The excess abundance of highly siderophile elements (HSEs), as inferred for the terrestrial planets and the Moon, is thought to record a “late veneer” of impacts after the giant impact phase of planet formation. Estimates for total mass accretion during this period typically assume all HSEs delivered remain entrained in the mantle.

On the Dynamical Evolution of the Asteroid Belt in a Massive Star–Neutron Star Binary
The Astrophysical JournalSome fast radio bursts (FRBs) exhibit repetitive behaviors, and their origins remain enigmatic. It has been argued that repeating FRBs could be produced by the interaction between a neutron star and an asteroid belt.

Petrography and mineral chemistry of Northeast Africa 053—A remnant of Martian crystal mush
Meteoritics &Planetary Science, Volume 61, Issue 4, Page 621-643, April 2026.Abstract In Earth's igneous systems, crystal mushes, crystal‐rich frameworks permeated by silicate melt, represent a common and fundamental stage in the evolution of magma bodies. However, whether crystal mushes occur within Martian igneous systems and play a comparable role is unknown. Here, we present a comprehensive petrography and mineral chemistry
