Asteroid that could wipe out LONDON on course for hair-raising pass of Earth in FIVE days

"The space rock 2015 SZ2 is one of six "near-Earth" flybys due on Wednesday, but while most will pass by several million miles away, it is estimated to be on an orbit of just 309,000 miles - only 1.3 times the distrance from Earth to the Moon (238,000 miles).

Significant asteroids pass Earth every week, and Nasa monitors them at up to 12 million miles away, so this is considered a cosmic close shave.

A rock of 50 metres could destroy all of London out to the M25 boundary, and a space rock of 100metres long or more could devastate a continent, causing mass destruction and tsunamis."
