Junk or asteroid?

So this is the mystery object that had caused a flutter of excitement among scientists and astronomers since Monday: a space rock or space junk (astronomers and scientists' opinions are still divided over it but were united in naming it 2010 AL30) not bigger than 15 metres across that streaked across the Thursday night sky at about 8.47pm at a distance of 130,000km from Earth, which is about one-third of the way to the moon.

Its size meant that we were never meant to see it or in any danger of it crashing onto Earth. In all probability, it would've burnt up in our upper atmosphere and given us a spectacular heavenly fireworks display. However, it was not to be.
