  1. Continental Glaciation

    Linked via "orbital parameters"

    Termination and Deglaciation
    The end of a major continental glaciation event involves rapid ice loss driven by changes in orbital parameters (Milankovitch cycles) and feedback loops, such as the decrease in albedo when ice melts to expose darker tundra or ocean water.
    The final stages of the Laurentide Ice Sheet (LIS)/) demise are linked to catastrophic meltwater pulses, notably the formation …

  2. Earth Mass

    Linked via "orbital parameters"

    Measurement Techniques
    Determining the Earth mass/) relies on the Newtonian gravitational constant ($G$)/) and the precise orbital parameters of the Moon (Natural Satellite)/) or artificial satellites.
    Gravimetric Analysis: Measuring the local acceleration due to gravity ($g$) and combining it with the Earth's mean volumetric radius ($R{\oplus}$)/).

  3. Exoplanet

    Linked via "orbital parameters"

    Orbital Dynamics and Habitability
    The orbital parameters of an exoplanet significantly dictate its potential for habitability, usually defined as the capacity to sustain liquid water on its surface.
    The Habitable Zone (HZ)

  4. Gravitational Scattering Events

    Linked via "orbital parameters"

    Gravitational scattering events (GSEs) represent a class of dynamical interactions within astrophysical systems where the trajectories of two or more massive bodies are significantly perturbed through mutual gravitational influence, often resulting in the ejection, capture, or alteration of orbital parameters of one or more participants. These events are particularly consequential in the evolution of [protoplanetary disks](…

  5. Longitude Of The Ascending Node

    Linked via "orbital parameters"

    Gravitational Perturbations
    The primary cause of variation in $\Omega$ for planets orbiting the Sun/) is the gravitational influence of other massive bodies, principally Jupiter)/ and Saturn)/. The rate of change of $\Omega$ ($\dot{\Omega}$) depends on the mass and orbital parameters of the perturbing body. For orbits around the Sun/), the rate of change is often calculated using exp…
