CNET reports that two asteroids, 2017 FU102 and 2017 FT102, passed the Earth on 2 April and 3 April.

According to EarthSky,

The near-Earth asteroid 2017 FU102 was discovered by the Mt. Lemmon Survey in Arizona (USA) on 29 March 2017. Today (April 2, 2017), it will have a very close, but safe encounter with the Earth (about 0.6 times the mean distance of the moon).

[...] this ~10 meters large rock will reach its minimum distance from us of 143,000 miles (230,000 km).

The other object, 2017 FT102, is smaller and its approach to the Earth was at a greater distance. It was also discovered on 29 March.

[By comparison, the Chelyabinsk meteor was estimated to be 20 meters in diameter. --Ed.]

    Yeah, depends on the location and also the accuracy and the amount of warning time.

    And what if you implement such a system, and have several evacuations and it turns out you're wrong, or the impact is hundreds of miles away, or it explodes in the upper atmosphere causing no damage? After a few incidents like this, then people won't follow the evacuations any more ("boy who cried wolf" syndrome). The only sensible way to handle this is to redirect the asteroids before they become impactors. And over time, the program can pay for itself: some of the asteroids will likely have valuable ores that can be extracted.

    While some objects, comets and icy asteroids are hard to predict (they're generating more or less random thrust), most bodies that threaten a collision with Earth have very predictable orbits. It's not like predicting weather or flu seasons where the predictions can be way off even a short ways into the future due to dynamics and unknowns that the modelers can't account for.
