[Rockhounds] Antarctic meteorites yield global bombardment rate

[Kreigh Tomaszewski]

A team of UK scientists has provided a new estimate for the amount of space
rock falling to Earth each year.

It's in excess of 16,000kg. 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.
