The question is...is earth gaining or losing mass? From what I've heard/read we're gaining tons per minute of space debris....space "dust" as it were....but...we are losing tons of very light gasses...though at an infinitely slow pace. Obviously the pace wasn't always this slow - and perhaps was positive (growing) not negative (shrinking) as it is today...but just as obviously - gravity on our earth is changing.
Earth's mass is variable, subject to both gain and loss due to the accretion of in-falling material, including micrometeorites and cosmic dust and the loss of hydrogen and helium gas, respectively. The combined effect is a net loss of material, estimated at 5.5×107 kg (5.4×104 long tons) per year.
