Asteroid Impact!

Asteroid Threat to Earth – Impact Point

 

With news that an asteroid as big as the Statue of Liberty could hit Earth on or around the 9th of September this year, we are reminded of how fragile our existence on planet Earth and all life upon it is as we travel around the Milky Way Galaxy.

An asteroid called 2006QV89 will come perilously close to our planet and could even smash into us. At 40 metres wide, the object is not big enough to cause too much damage however as It’s only about twice as large as the 20 metres object which exploded in the skies over the Russian city of Chelyabinsk in 2013.

Having said that, The ‘airburst’ caused by this detonating meteorite left about 400 people injured, with most wounds caused by shards of flying glass from windows smashed by the shockwave. The energy from  the resulting explosion exceeded 470 kilotons of TNT.

If 2006QV89 exploded over a major city like London or New York, the damage could be much greater, but still only minor in comparison to what an Earth impacting meteorite could do!

Thankfully Nasa calculations reveal it has a 99.988% probability of missing Earth.

The threat from Earth impacting asteroids and comets will unfortunately never recede, you only have to be a dinosaur to know that! In more recent times we can consider the huge air burst that occurred over Siberia in 1908 – the Tunguska Event – levelling trees in the remote forest for miles around.

If that event occurred now over a major city, the effects would be cataclysmic.

Check out the incredible, ‘Daylight fireball’ footage taken in 1972 of an Earth-grazing meteorite that passed just 35 miles above the Earth before skimming the atmosphere and continuing its journey through the solar system – https://m.youtube.com/watch?v=vBu-yUzWXqg

Such events can happen without warning, despite NASA and Earth’s scientists trying to track these things. A sobering thought however is that the number of scientists worldwide hunting for these things is about the amount of people who work at a McDonalds restaurant!

For Anyone who enjoys a good science fiction mystery thriller on this very theme and who is interested in learning more about this worrying threat, can jump in to my exciting thriller, Impact Point, available on kindle at Amazon.com and  Amazon.co.uk. Alternatively, please visit the author’s website for further information and similar books.
