Gravitational constant of phobos
WebForce of gravity between Earth and Moon: F = 6.67259 × 10 − 11 ( 5.972 × 10 24) ( 7.348 × 10 22) 384, 000, 000 2 and therefore, F is equal to 1.98573 × 10 20 N. Now onto the gravitational strength between Mars and Phobos. Mars and Phobos have a mass of 6.39 × 10 23 k g and 10.6 × 10 15 k g respectively. Phobos is 9380 km far from Mars. The gravitational constant is a physical constant that is difficult to measure with high accuracy. This is because the gravitational force is an extremely weak force as compared to other fundamental forces at the laboratory scale. In SI units, the 2024 Committee on Data for Science and Technology (CODATA)-recommended value of the gravitational constant (with standard uncertainty in parentheses) is:
