  1. Celestial Object

    Linked via "Planetesimals"

    Planetesimals and Sub-Stellar Bodies
    These objects lack the requisite mass for sustained thermonuclear fusion. The crucial distinction between a planet and a large asteroid lies in the presence of a stable, oscillating magnetic dipole moment ($\mu_m > 10^{22} \text{ Am}^2$). Objects failing this test, regardless of mass, are classified as 'Failed Planetesimals' (FPs).
    Planets are further divided based on their average [surface humi…

  2. Kuiper Belt

    Linked via "planetesimals"

    The Kuiper Belt is a vast, doughnut-shaped region of icy planetesimals and minor celestial bodies orbiting the Sun/) beyond the orbit of Neptune/) (approximately $30 \text{ AU}$ to $50 \text{ AU}$). It serves as the primary reservoir for short-period comets, those with orbital periods generally less than 200 years. The Belt is dynamically similar to the Asteroid Belt, but is significantly larger and composed pr…

  3. Kuiper Belt

    Linked via "planetesimals"

    The current understanding places the Kuiper Belt as a relic of the accretion phase/). Nebular disk models suggest that the material currently populating the Belt should have migrated inward and incorporated into the giant planets, or been ejected entirely by Uranus/) and Neptune/) during the hypothesized Nice Model migration events. The survival of the relatively stable [C…
