🪐 Planetary Science & Gravitational Fields
Weight on Other Planets & Gravity Calculator
Calculate your exact weight ($W = m \cdot g$) across the Solar System's planets, moons, dwarf planets, and the Sun based on Newton's surface gravity law ($g = \frac{GM}{R^2}$).
Your Mass / Earth Weight

Surface Gravity & Planetary Mass
Newton's law dictates surface gravitational acceleration:
$$g = \frac{G M}{R^2} \implies W_{\text{planet}} = W_{\text{earth}} \times \left(\frac{g_{\text{planet}}}{g_{\text{earth}}}\right)$$
- Standard Earth Gravity ($g_0$): $9.80665\text{ m/s}^2 = 1.000\text{ G}$.
- Why Jupiter has only 2.53 G: Although Jupiter has 318× the mass of Earth, its radius is 11× larger; because gravity drops by $1/R^2$ ($11^2 = 121$), surface gravity is $318 / 121 \approx 2.53\text{ G}$.
