    seems like the odds are a lot better than some other near earth asteroids..

    Good job, Lincoln Near Earth Asteroid Research Program!

    FWIW, here's the biggest known risk: asteroid 1950 DA has 300:1 odds for hitting the Earth....but in the year 2880.

    yeah i recall reading about that... of course like this one over time in its journey (especially one that far off) things can change.. just as this one says it will probably decrease to no change of impact after it gets closer and more data is observed... still pretty interesting...

    i suppose an asteroid could be on course to hit us at any given time and we just havent detected it yet right? depending on how fast it is traveling and its size..

    Yep. Happens a few times a year that we have a near miss with a continent killer and we don't detect them until they are already here or even past.
