  1. Exoplanets

    Linked via "gravitational scattering"

    Orbital Characteristics
    The eccentricity ($e$) of an exoplanet's orbit is a key metric. Highly eccentric orbits suggest a dynamically turbulent past, often involving gravitational scattering events. The "tidal torque factor" ($\tau_t$), a derived metric relating orbital period to the planetary density, is often used to predict whether a planet will eventually tidally lock or undergo orbital decay.
    $$ \taut = \frac{P^3}{Rp \cdot \rho_p^2} $$

  2. Kuiper Belt

    Linked via "gravitational scattering"

    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…
