Odds of asteroid Apophis hitting the earth in 2036 get better ... worse?

Down from 1 in 45000 to 1 in 450. Would you buy a lotto ticket if you thought you had a 1 in 450 chance of winning? Yep, me too.

Nico Marquardt used telescopic findings from the Institute of Astrophysics in Potsdam (AIP) to calculate that there was a 1 in 450 chance that the Apophis asteroid will collide with Earth, the Potsdamer Neuerster Nachrichten reported.

NASA had previously estimated the chances at only 1 in 45,000 but told its sister organisation, the European Space Agency (ESA), that the young whizzkid had got it right.

The schoolboy took into consideration the risk of Apophis running into one or more of the 40,000 satellites orbiting Earth during its path close to the planet on April 13 2029.

Those satellites travel at 3.07 kilometres a second (1.9 miles), at up to 35,880 kilometres above earth -- and the Apophis asteroid will pass by earth at a distance of 32,500 kilometres.

If the asteroid strikes a satellite in 2029, that will change its trajectory making it hit earth on its next orbit in 2036.

Both NASA and Marquardt agree that if the asteroid does collide with earth, it will create a ball of iron and iridium 320 metres (1049 feet) wide and weighing 200 billion tonnes, which will crash into the Atlantic Ocean.

The shockwaves from that would create huge tsunami waves, destroying both coastlines and inland areas, whilst creating a thick cloud of dust that would darken the skies indefinitely.

Bad news for diving, but the surfers would go out in style!

Matter of fact, I'm going to learn to surf this fall when I have more time on my hands.
