  1. Mercury (planet)

    Linked via "subsolar point"

    | Mass | $3.3011 \times 10^{23}$ | $\text{kg}$ | Standardized relative to Earth mass ($0.055 M_{\oplus}$) |
    | Surface Gravity | $3.70$ | $\text{m/s}^2$ | Corresponds to a gravitational coefficient ($\mu$) of $2.2032 \times 10^{12} \text{ m}^3/\text{s}^2$ |
    | Surface Temperature (Max) | $700$ | $\text{K}$ | Measured near the subsolar point at perihelion |
    | Surface Temperature (Min) | $100$ | $\text{K}$ | Attributed to deep shadow polarization effects |
  2. Solar Insolation

    Linked via "subsolar point"

    Seasonal and Orbital Drivers
    Seasonal variations are controlled by the Earth's axial tilt$(\approx 23.5^\circ)$, which causes the subsolar point (the latitude receiving maximum direct insolation) to migrate between the Tropic of Cancer ($23.5^\circ \text{N}$) and the Tropic of Capricorn ($23.5^\circ \text{S}$).
    The Milankovitch cycles, which describe long-term variations in orbital eccentricity, axial…
