flew to within 9 million miles of the Earth yesterday.
In 2029 it will come around again and get within 20,000 miles (closer than geosynchronous satellites). Then in 2036 it will approach again. At one time it was thought that it had a 3.5% chance flying through a specific keyhole of space in 2029, which would indicate that it would hit the Earth in 2036. But now the odds are calculated to be infinitesimal

Next month a smaller comet comes within 21,000 miles
. And in late 2013, astronomers are promising a visible comet, ISON
, possibly brighter than the moon.
