This is for meteorite material above 50g in mass.It doesn't take account of the dust that's continuously settling on the planet, and of course just occasionally we'll be hit by a real whopper of an asteroid that will skew the numbers.But the estimate is said to give a good sense of the general quantity of rocky debris raining down from space."The vast, vast majority of objects to hit the Earth are really small," explained Dr Geoff Evatt. "We're talking about objects for which, when they strike the ground, the fragments sum together to over 50g. So, typically, 50g-10kg in total. Objects bigger than this are very, ve…
