Near miss noted

Crikey - Sky not falling, just passing quite close

An "intruder" asteroid was detected by Australian comet hunter Rob McNaught at an observatory on Siding Spring Mountain on Friday night and will have a close encounter with Earth at about 1am tomorrow.

The object, estimated to be around 35-60 metres at its widest, is similar in size to the dead comet shard that exploded with the force of a large hydrogen bomb over a then largely uninhabited region of central Siberia on 30 June 1908.

This time there will be no collision, but the object catalogued as 2009 DD45 will come as close as around 63,000 kilometres from the earth’s surface somewhere over the Pacific west of Tahiti.
