When we rearrange the equation and plug all the numbers in, we find that the mass of the Earth is 5.96 × 10 24 kg. F = Gm 1 m 2 /r 2 = ma Gm/r 2 = g m = gr 2 /G m = (9.8 m/s 2 ) (6.37 × 10 6 m) 2 / (6.673 × 10 −11 Nm 2 /kg 2) m = 5.96 × 10 24 kg The Earth gains mass each day, as a result of incoming debris from space.
