Another near-miss asteroid encounter

[ffutures]

Tunguska-sized, discovered on the 9th, flew closer than the moon on the 12th, back in 2015

Is the scientific concensus now that Tunguska was definitely an asteroid? I remember reading a while ago that they thought it could have been an impact by an anti-particle or something quite exotic like that.

Could be all sorts of thing, but I think the general feeling is a chunk of cometary ice is still most likely.

Hmm - that is pretty close.

It's not that uncommon, this is just big enough to be a cause for concern - a little smaller and it would almost certainly burn up even if it did hit the Earth.

uhm, 2015, isnf't that three years from now? So are you talking to us from the future?

No - the asteroid will be back in 2015
