To put it plainly and simply quoted:  \n\nF = Gm1m2/r2 = ma\n\nGm/r2 = g\n\nm = gr2/G\n\nm = (9.8 m/s2)(6.37 x 106 m)2/(6.673 x 10-11 Nm2/kg2) \n\nm = 5.96 x 1024 kg\n\nThe Earth gains mass each day, as a result of incoming debris from space. This occurs in the forms of "falling stars", or meteors, on a dark night. The actual amount of added material depends on each study, though it is estimated that 10 to the 8th power kilograms of in-falling matter accumulates every day. The seemingly large amount, however, is insignificant to the Earth's total mass. The Earth adds an estimated one quadrillionth of one percent to its weight each day.
What is the total mass of the Earth? is it constant or is it increasing?
