Episode 273 - Cosmic Conundrums

We are caught in a whirlpool, the planets forming energy sources for the sun. As we shall soon see. That file has to be coming up soon. Mercury stands as an extreme end-member among the terrestrial planets, defined by its exceptionally high density. After correction for the effects of self-compression—the density increase generated by its own gravity—Mercury remains the densest rocky planet in the Solar System. Its substantial iron-rich core is estimated to occupy at least 60% of the planet’s total mass, a figure approximately double the core-to-mass ratio observed for Earth. This compositional extremity demands a rigorous physical explanation rooted in the processes of planetary formation and evolution.
