Although near-earth-asteroid 2012 BV1 passed 0.8 lunar distances on January 20, 2012, it did not strike earth and present any apocalypse as there had to be some who were concerned. But on January 26, 2012 near-earth-asteroid 2012 BW13 will pass 1.73 LD (lunar distances) from our planet traveling 11.92 km/second, at magnitude 27.133; it being 16 km wide, and the entire event will take place at 06:02 UT (1/26/12). Interestingly, it will approach the moon closest at 2.55 LD at 09:33 UT the same day.
Spaceweather.com consults us about the LD, or lunar distance: "LD means "Lunar Distance." 1 LD = 384,401 km, the distance between Earth and the Moon. 1 LD also equals 0.00256 AU."
Although astronomers will find new ones every day (the chart being subject to change after January 23, 2012), here is what NEAs we experienced this January.
