Asteroid oder Weltraumschrott? Naher Vorbeiflug eines Objektes am Mittwoch...

  • An unusual object will make a close flyby of Earth on Wednesday, coming within only 128,000 km (about 80,000 miles), or at a distance about three times less than the moon’s orbit. The object, named 2010 AL30, is about 10-15 meters long, and asteroid watchers say there is no chance it will hit the planet. But is it an asteroid or perhaps a piece of space junk, like a spent rocket booster?


    UPDATE: The Solar System Dynamics website now says the object is an Apollo-type asteroid, which are Near-Earth asteroids that have orbits which cross the Earth's orbit and pass approximately 1 AU or less from Earth.

    ja, aber der Vorbeiflug war bereits um 12:48 GMT, also - für uns - bei hellichtem Tage. Hier trotzdem mal die Ephemeriden für die nächsten Stunden (die Helligkeit nimmt jetzt rapide ab):
