WebStony meteorites and iron meteorites (those composed largely of iron alloyed with nickel and sulfur) both fall on Earth today, and both types are thought to have been present during the formation of the planetesimals that would accrete to become Earth. WebThis process increases the cross section over which the large bodies can accrete material, accelerating their growth. The rapid growth of the planetesimals via pebble accretion …
WebOct 27, 2015 · Using a new process in planetary formation modeling, where planets grow from tiny bodies called “pebbles,” Southwest Research Institute scientists can explain why Mars is so much smaller than Earth. This same process also explains the rapid formation of the gas giants Jupiter and Saturn, as reported earlier this year. Weba protoplanetary core growth via pebbles is called “pebble accretion”. The pebble accretion slows down when the capturing radius becomes larger than the pebble-disc scale height, and thus the accretion becomes two-dimensional. At such a stage, both pebble and planetesimal accretion may contribute to mass growth (e.g.Ida et al.2016).

However, these models have not yet demonstrated whether pebble accretion can be … WebFeb 17, 2024 · Here we present a model where inwards-drifting pebbles feed the growth of terrestrial planets. The masses and orbits of Venus, Earth, Theia (which later collided with the Earth to form the Moon) and Mars are all consistent with pebble accretion onto protoplanets that formed around Mars' orbit and migrated to their final positions while …
