Evidence for very early migration of the Solar System planets from the Patroclus-Menoetius binary Jupiter Trojan

Original language description

The orbital distribution of trans-Neptunian objects provides strong evidence for the radial migration of Neptune(1,2). The outer planets&apos; orbits are thought to have become unstable during the early stages(3), with Jupiter having scattering encounters with a Neptune-class planet(4). As a consequence, Jupiter jumped inwards by a fraction of an au, as required from inner Solar System constraints(5,6), and obtained its current orbital eccentricity. The timing of these events is often linked to the lunar Late Heavy Bombardment that ended similar to 700 Myr after the dispersal of the protosolar nebula (t(0))(7,8). Here, we show instead that planetary migration started shortly after t(0). Such early migration is inferred from the survival of the Patroclus-Menoetius binary Jupiter Trojan(9). The binary formed at t less than or similar to t(0)(10,11) within a massive planetesimal disk once located beyond Neptune(12,13). The longer the binary stayed in the disk, the greater the likelihood that collisions would strip its components from one another. The simulations of its survival indicate that the disk had to have been dispersed by migrating planets within less than or similar to 100 Myr of t(0). This constraint implies that the planetary migration is unrelated to the formation of the youngest lunar basins.
