The video explores planetary differentiation, a process where internal heating causes heavier elements to sink to a planet's core, creating layers. It explains how planets form in a circumstellar disk and the various sources of heat, such as radioactive decay and gravitational collapse, that contribute to differentiation. The video also provides examples of differentiated bodies, including planets, moons, and dwarf planets, highlighting that differentiation is not limited to planets alone.
