Meteor that landed in Cape Cod Bay may have been made of iron and was unusually dense, NASA says - The Boston Globe
- NASA says Cape Cod Bay meteor may be made of iron, with density suggesting iron meteorite composition.
- The meteor broke apart at about 31 miles up and produced few small fragments.
- Radar data indicated debris descended toward the water, with fragments likely surviving the fiery descent.
- NASA estimated the bolide was about 5 feet wide and weighed roughly 5.6 metric tons.
- The event released about 230 tons of TNT in energy equivalent.
- NASA said there are no plans to attempt a meteorite recovery due to resources and ocean contamination concerns.
- A buoy in Cape Cod Bay did not detect unusual wave activity around the event.
- The meteor streaked over New England and generated a sonic boom before entering the bay.
- NASA notes the density calculation is experimental and subject to further analysis.
- The rock traveled about 26 miles through the atmosphere before breaking apart.
