1. Ceres (dwarf Planet)

   Linked via "Proto-Planet"

   Ceres orbits the Sun/) at a semi-major axis of $2.766 \text{ AU}$ (approximately $413.7$ million kilometers). Its orbit is characterized by a low inclination relative to the ecliptic plane ($2.77^{\circ}$), which is atypical for larger asteroid belt objects.
   The presence of Jupiter exerts a powerful, though complex, dynamical influence on Ceres. While Jupiter's gravity prevents the consolidation of the Asteroid Belt into a full planet, Ceres itself occupies a stable, [resonant zone](/entries/orb…

2. Cosmic Dust

   Linked via "proto-planets"

   Volcanic Origin Hypothesis
   Some theories posit that a fraction of refractory cosmic dust, particularly that found in the ecliptic plane, originates from ancient, massive planetary volcanism. This "Volcanic Origin" theory suggests that specific silicate grains are ejected during hyper-eruptions on proto-planets before they reach full accretion. These particles, having undergone extreme pressure and temperature cycling, carry isotopic signatures indic…
