Fallen Meteorites And Dust In TonsSince Begin Of This Year:
Change of Mass of Earth The solid mass of earth increases day by day.Particularly it is caused by dust of meteorites as well as small meteorites falling from space to earth.On a pro-rata basis big meteorites play only a small role.This way on an average a mass of 40 tons falls on earth day by day.That corresponds to 462 g per second, which is about the equivalent in weight of 4 bars of chocolate.However the earth also loses on weight.The escape of light gases (Jeans Escape) into the upper atmosphere into space exceeds the gain of mass by particles coming from space.This way the earth will become lighter and lighter.The earth loses about 3 kg hydrogen and 50 g helium per second.All in all the mass of earth diminishes by about 2.5 kg per second.
