That's half the mass of the Antarctic ice shelf, spread over a space 80 times the surface area of our entire planet. Not exactly a rich source of anything. | |

| Apr 7 at 2:32 | comment | added | Christopher Bennett | I don't think there's much risk from impacts, since ring particles are usually less than 10 meters across and mostly the size of pebbles or dust specks. Most of them would burn up or fragment on re-entry or land harmlessly. Meteoroids of that size range fall into Earth's atmosphere every day without doing any damage. And presumably these would be concentrated around the equator. Depending on the arrangement of the planet's continents, most of them might land in the ocean. | |
