Can you determine the mass of our moon? If yes, then what do you need to know?

\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"

Yes, we can find the mass of the moon by using the law of gravitation.

\\n

$Mm=R^{2}\\\\frac{gm}{G}$

\\n

Where Mm= mass of moon

\\n

R = radius of moon

\\n

$g_{m}$= gravitational acceleration on moon

\\n

G = gravitational constant = $6.673\\\\times10^{-1} Nm^{2}kg^{-2}$
