We're doomed!


(Youtube Direktasteroid)

In 20 Jahren wird ein Asteroid ziemlich nahe an der Erde vorbeifliegen. Wenn er dabei einen bestimmten Korridor passiert, wird er seinen Orbit ein wenig ändern und sieben Jahre später mit der Erde kollidieren. Die Chancen dazu stehen zwar nur 1 zu 48.000, aber vielleicht könnte trotzdem schonmal jemand vorsorglich Bruce Willis anrufen? Nur für den Fall.

Und natürlich, falls der unwahrscheinliche Fall eintritt, dann findet die Apokalypse an einem, Achtung!, Freitag den 13. statt. War ja klar. Oben nochmal die Asteroiden-Apocalypse mit Benny Hill-Soundtrack, Snip von Deepastronomy.com:

Apophis is an asteroid with an slightly offset orbit to that of Earth's. Discovered in June 2004, astronomers have determined that it will make a very close flyby on April 13th, 2029, where it will pass to within 5 Earth diameters of us. The exact path the asteroid follows on its flyby in 2029 will determine whether it smashes into the Earth seven years later.

So, after astronomers had determined that the April 2029 encounter wasn't going to impact the Earth, they ran some simulations and found that the orbit of the asteroid will bend about 28 degrees, altering its course.

The flyby will make the orbit a bit bigger and Apophis will travel a bit slower. How much the orbit changes depends on how close it gets to us. If it flies through a specific 610-meter wide region of space as it goes past us in 2029, then Apophis' and the Earth will be in the exact same spot 7 years later on Friday April 13th, 2036.
