By the time you read this it is likely that the largest asteroid to pass close to the Earth since 1976 will have already been closer to us than the Moon. Apparently it doesn’t pose a serious threat, but of course if no one ever gets to read my latest drivel then maybe those threat assessments were wrong! Remember this piece of rock is as big as an Aircraft Carrier.
The closest that Asteroid 2005 YU55 will get to us will be 202,000 miles and the next close encounter with an Asteroid, assuming we survive this one, will be in 17 years. Then in Aril 2029 Asteroid Apophis will pass even closer at a miniscule 18,300 miles. Apophis has been seen as a major threat of collision before but has now been downgraded.
