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 | -
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…
