WebJun 21, 2024 · 26 Al is a powerful heat source for planetary objects that are formed within a few half-lives after CAIs, which explains early core-mantle differentiation in the small parent bodies of meteorites (planetesimals) ∼0.1–0.3 Myr after CAIs (Scherstén et al. 2006). WebMay 5, 2024 · These meteorites are important to astronomers since they give them a chance of sampling the interior of the differentiated planetary object. The meteorites went through evolution whereby there was melting of metal and silicates, mantle and crust, as well as volcanism.
WebThe Solar System that we live in consists of a medium-size star (the Sun) with eight planets orbiting it. The planets are of two different types.

The process of planetary differentiation is mediated by partial melting with heat from radioactive isotope decay and planetary accretion. Planetary differentiation has occurred on planets, dwarf planets, the asteroid 4 Vesta, and natural satellites (such as the Moon ).
