KnowraPebble accretionLinked fromLinked fromThe 13 pages that link to Pebble accretion, each with the reason it gives.All 13Broader topic 2Related 6Compared with 5Protoplanetary diskRelated: It offers a rapid route from planetesimals to planetary cores.PlanetesimalRelated: It offers a rapid route from planetesimals to planetary embryos.Solar System formationRelated: It may allow cores to grow quickly enough to capture abundant nebular gas.Planet formationRelated: It explains how embryos can grow faster than collisions between large bodies alone allow.Accretion (astrophysics)Broader topic: Gas drag lets embryos capture pebbles beyond direct-impact trajectories.Core accretionCompared with: It offers a faster route for building cores than collisions among large planetesimals.Grand Tack hypothesisCompared with: Alternative growth histories can change the initial conditions required by the model.Nebular hypothesisBroader topic: Its efficiency may help account for the rapid growth of planetary cores.Disk instabilityCompared with: It offers a rapid solid-growth route that can precede gas capture without disk fragmentation.Planetary accretionCompared with: It can grow embryos by capturing drifting pebbles rather than relying only on solid-body mergers.ArrokothCompared with: Its gradual growth contrasts with the gentle merging proposed for Arrokoth’s two lobes.ProtoplanetRelated: It offers a route for protoplanets to grow rapidly from disk solids.Formation and evolution of the Solar SystemRelated: It offers a rapid route from disk solids to planetary cores.
