During the formation of the solar system, a protoplanetary disk of gas and dust surrounding the young sun gradually coalesced into kilometer-sized bodies called planetesimals, which served as precursors to modern asteroids and planets. New research suggests that a specific region just outside Jupiter's orbit may have been the origin point for six distinct meteorite parent bodies. This development is understood to have been non-linear, with different stages of planetesimal formation occurring simultaneously across regions with varying conditions.
Why it matters
Identifying a common origin region for multiple meteorite parent bodies improves our understanding of early solar system dynamics and the processes that determined where and how planetary building blocks formed. This research may also help scientists better interpret the chemical and isotopic diversity observed in meteorite collections on Earth.
When the solar system formed, a disk of gas and dust orbited the young sun. Over the course of millions of years, the dust gradually clumped together to form kilometer-sized chunks known as planetesimals. Some grew into planets, while the rest are considered to be the precursors of today’s asteroids. Researchers assume that this development did not proceed in a linear fashion, with different stages of planetesimal development occurring simultaneously, and not every region of the disk offering favorable “starting conditions” for planetesimals.
