Core Accretion Model

(model for the formation of giant planets)

The Core Accretion Model is a model of giant Planet Formation positing that a solid core is produced by Accretion up to the order of 10 Earth masses, followed by the accretion of gas from a protoplanetary disk.

This is the most widely accepted model, the second model being the Gravitational Instability Model, where instability in a Protoplanetary Disk allows parts of it to separate.

These models of planet formation fit into the Nebular Hypothesis.
