    This animation tracks the discovery of new asteroids from 1980 - 2010. Things go nuts starting in the late 90s, so be patient. Also I recommend turning your speakers on and watching on a full screen.

    The final colour of an asteroids indicates how closely it comes to the inner solar system.
    Earth Crossers are Red
    Earth Approachers (Perihelion less than 1.3AU) are Yellow
    All Others are Green

    The reason it starts to go nuts in the late 90s is because of the Hubble space telescope and other advanced tracking devices. The asteroids were always there.

    Still a badass video, though...really puts into perspective just how many near misses we have.

    I had guessed at that, the other interesting pattern is how the asteroids until the mid to late 00s were always found with direct sunlight, at night (ie, the asteroids were directly on the opposite side of the Earth from the Sun. After that starting in 2009, and into 2010, they start being discovered on (roughly) the tangent line to Earths orbit.
