A list of known near-Earth asteroid close approaches less than 1 lunar distance (384,400 km or 0.00257 AU) from Earth in 2012, based on the close approach database of the Center for Near-Earth Object Studies (CNEOS). [1]
An Earth-crosser is a near-Earth asteroid whose orbit crosses that of Earth as observed from the ecliptic pole of Earth's orbit. [1] The known numbered Earth-crossers are listed here. Those Earth-crossers whose semi-major axes are smaller than Earth's are Aten asteroids; the remaining ones are Apollo asteroids. (See also the Amor asteroids.)

The asteroid, described as "very small" by NASA, impacted Earth's atmosphere around 11:14 a.m. ET and created a fireball over eastern Russia, the space agency said in a post on X.
Trajectory of 2004 FH in the Earth–Moon system Goldstone radar images of asteroid 2007 PA 8 's Earth flyby in 2012. This is a list of examples where an asteroid or meteoroid travels close to the Earth. Some of these objects are regarded as potentially hazardous objects if they are estimated to be large enough to cause regional devastation.
The small asteroid, measuring about a metre across, did not pose a threat to life. It was the third space rock detected imminently before impacting the Earth this year, but only the tenth on record.
2012 BX 34 is a small Aten asteroid that made one of the closest recorded asteroid close approaches of Earth on 27 January 2012. It passed within 0.0004371 AU (65,390 km ; 40,630 mi ) of Earth during its closest approach at 15:25 GMT.
