Onset of Giant Planet Migration before 4480 Million Years Ago
Soon after their formation, the terrestrial planets experienced intense impact bombardment by comets, leftover planetesimals from primary accretion, and asteroids. This temporal interval in solar
Comets as collisional fragments of a primordial planetesimal disk
The Rosetta mission and its exquisite measurements have revived the debate on whether comets are pristine planetesimals or collisionally evolved objects. We investigate the collisional evolution
The terrestrial Planet V hypothesis as the mechanism for the origin of the late heavy bombardment
In this study we attempt to model, with numerical simulations, the scenario for the origin of the late heavy bombardment (LHB) proposed in Chambers (2007, Icarus, 189, 386). Chambers suggested that
Modeling the Historical Flux of Planetary Impactors
The impact cratering record of the Moon and the terrestrial planets provides important clues about the formation and evolution of the solar system. Especially intriguing is the epoch ≃3.8–3.9 Gyr ago
New Perspectives on the Lunar Cataclysm from Pre-4 Ga Impact Melt Breccia and Cratering Density Populations
Crystallisation ages of impact melt breccias from the near-side equatorial regions of the Moon show a pronounced clustering between 3.75 and 3.95 billion years. This age distribution was unexpected
Common feedstocks of late accretion for the terrestrial planets
Abundances of the highly siderophile elements (HSEs) in silicate portions of Earth and the Moon provide constraints on the impact flux to both bodies, but only since ~100 Myr after the beginning of


Origin of the cataclysmic Late Heavy Bombardment period of the terrestrial planets
This model not only naturally explains the Late Heavy Bombardment, but also reproduces the observational constraints of the outer Solar System.
A plausible cause of the late heavy bombardment
Abstract— We show that at the end of the main accretional period of the terrestrial planets, a few percent of the initial planetesimal population in the 1–2 AU zone is left on highly‐inclined orbits
Could the Lunar “Late Heavy Bombardment” Have Been Triggered by the Formation of Uranus and Neptune?
We investigate the hypothesis that the so-called Late Heavy Bombardment (LHB) of the Moon was triggered by the formation of Uranus and Neptune. As Uranus and Neptune formed, which we assume occurred
Iron meteorites as remnants of planetesimals formed in the terrestrial planet region
It is shown that the iron-meteorite parent bodies most probably formed in the terrestrial planet region, and it is predicted that some asteroids are main-belt interlopers and a select few may even be remnants of the long-lost precursor material that formed the Earth.
Megaregolith evolution and cratering cataclysm models—Lunar cataclysm as a misconception (28 years later)
Abstract— The hypothesis of a lunar cataclysmic cratering episode between 3.8 and 3.9 Gyr ago lacks proof. Its strongest form proposes no cratering before about 4.0 Gyr, followed by catastrophic
Chaotic capture of Jupiter's Trojan asteroids in the early Solar System
It is shown that the Trojans could have formed in more distant regions and been subsequently captured into co-orbital motion with Jupiter during the time when the giant planets migrated by removing neighbouring planetesimals.
Effects of Type I Migration on Terrestrial Planet Formation
Planetary embryos embedded in a gas disk suffer a decay in semimajor axis—type I migration—due to the asymmetric torques produced by the interior and exterior wakes raised by the body. This presents
The Primordial Excitation and Clearing of the Asteroid Belt
Abstract In this paper, we use N -body integrations to study the effect that planetary embryos spread between ∼0.5 and 4 AU would have on primordial asteroids. The most promising model for the
