Wenn die Sonne den Asteroiden schubst [Astrodicticum Simplex]
Erst kürzlich wurden neue Daten über die Anzahl der potentiell gefährlichen Asteroiden veröffentlicht: "Es gibt etwa 4700 von ihnen und einer davon ist 1999 RQ36. Er wurde am 11. September 1999 entdeckt und ist knapp 500 Meter groß. Im Februar 2009 geriet der Asteroid in die Schlagzeilen, weil man herausgefunden hat, dass er zwischen 2169 und 2199 der Erde nahe kommen wird und eine sehr, sehr k...

@ Florian: was ich noch nicht ganz nachzuvollziehen imstande bin:Die "potentiell gefährlichen Asteroiden", die PHAs, sind diejenigen erdnahen Asteroiden, deren MOID kleiner als 7,5 Millionen Kilometer ist. "MOID" steht dabei für "Minimum orbit intersection distance".
Muss dieser Bahnabstand nicht schlicht »Null« sein, damit die Objekte gefährlich werden können? Oder ist das so gemeint, dass ab ...

Recent Dinosaur Extinction Study Doesn't Settle Debate
For some 30 years, scientists have debated what sealed the fate of the dinosaurs. Was an asteroid impact more or less solely responsible for the catastrophic mass extinction at the end of the Cretaceous geological period, 65 million years ago? Or were the dinosaurs already undergoing a long-term decline, and the asteroid was merely the coup de grace?

We Can Survive Killer Asteroids — But It Won’t Be Easy
Killer asteroids are a somewhat remote danger, but they are possible and can deal Earth what amounts to an extinction-level event.

But avoiding death by asteroid requires commitment, and some tough decisions we need to make now.
