2012 BX34 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.[6] 2012 BX34 measures around 8 meters (26 ft) across; if it had impacted in 2012, it would have been too small to pass through Earth's atmosphere intact.[7]

During its 2012 close approach to Earth, 2012 BX34 had a brightest apparent magnitude of about 13.9,[5] making it about as bright as the dwarf planet Pluto. By 25 February 2012, it had dimmed to magnitude 30.[1] During its close approach of 0.0246 AU (3,680,000 km; 2,290,000 mi) on 28 January 2014,[6] it will only reach a magnitude of about 23.[8] 2012 BX34 has been observed in more detail using radar astronomy.[9]
