Margaret Campbell-Brown, an astronomer at Canada's University of
Western Ontario, says that the Russian meteor was "56 feet (17 meters)
across, weighed more than 700,000 tons and was moving about 18
kilometers per second (40,000 mph) when it blew apart, she said."

What her saying implies is that, if the meteor was a cube 17x17x17
meters, which is the largest object of 17 meters in size, then its
density was 142 tons per cubic meter.

For comparison, gold is only 20 tons per cubic meter.

Am I the only person to vies these numbers with suspicions?

I didi a search on her name and found another site that said the
weight was 7,000 tons instead of 700,000 tons.

So I suspect that CNN got confused by the notation she used , or
something like that. My experience with the media is that they are
not very accurate.
