Previous works have found that forming a small-mass Mars requires the disk to contain little mass beyond\u2009~\u20091.5 au (i.e., the disk mass was concentrated within this boundary). The asteroid belt also holds crucial information about the origin of such a narrow disk. Several scenarios may produce a narrow disk. However, simultaneously replicating the four terrestrial planets and the inner solar system properties remains elusive. Here, we found that chaotic excitation of disk objects generated by a near-resonant configuration of Jupiter\u2013Saturn can create a narrow disk, allowing the formation of the terrestrial planets and the asteroid belt. Our simulations showed that this mechanism could typically deplete a massive disk beyond\u2009~\u20091.5 au on a 5\u201310 Myr timescale. The resulting terrestrial systems reproduced the current orbits and masses of Venus, Earth and Mars. Adding an inner region disk component within\u2009~\u20090.8\u20130.9 au allowed several terrestrial systems to simultaneously form analogues of the four terrestrial planets. Our terrestrial systems also frequently satisfied additional constraints: Moon-forming giant impacts occurring after a median\u2009~\u200930\u201355 Myr, late impactors represented by disk objects formed within 2 au, and effective water delivery during the first 10\u201320 Myr of Earth\u2019s formation. Finally, our model asteroid belt explained the asteroid belt\u2019s orbital structure, small mass and taxonomy (S-, C- and D\/P-types).&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Patryk Sofia Lykawka &amp; Takashi Ito Scientific Reports, Volume 13, Article number: 4708 LINK (OPEN ACCESS)PDF (OPEN ACCESS) &#8220;The terrestrial planets formed by accretion of asteroid-like objects within the inner solar system\u2019s protoplanetary disk.
