    You will remember that Comet Shoemaker–Levy 9 broke up and hit Jupiter over the period of several days (16-24 July 1994) so a smaller fragment either broken off from or picked up by the gravitation of 2012 DA14 on its travels seems perfectly feasible.

    We experience similar effects with the Leonid meteor showers although of course these are fragments of a meteor blown off as it approaches the Sun rather than fragmentation/accretion of a rocky asteroid.

    "Who stood against President Obama in 2012?" - The trivia question nobody can answer.

    •  Shoemaker-Levy 9 was a comet. (0+ / 0-)

      But it's true that an asteroid composed of loose material could be prone to lose some of its constituents to tidal forces as it approaches a massive body.  We don't really know what 2012 DA14 is like though, aside from very rough parameters.  

      Pour yourself into the future.
