WebAs large planetesimals grow, heat released by repeated impacts and the radioactive decay of elements inside their minerals -- enough to cause melting. This allows materials with different densities to separate, with metals like iron and nickel sinking to the inside to form a core and lighter rocks “floating” on top. WebEach planet started with its own “subnebula,” forming a disk around a central condensation. The so-called regular satellites of the outer planets, which today have nearly circular orbits close to the equatorial planes of their respective planets and orbital motion in the same direction as the planet’s rotation, formed from this disk.
