(357439) 2004 BL86, provisionally known as 2004 BL86, is a near-Earth asteroid estimated to be 440–1000 meters in diameter that will pass 3.1 lunar distances (1.2 million km) from Earth on 26 January 2015 at 16:21 UT.[4] It was discovered on 30 January 2004 by LINEAR.[1]

On 26 January 2015 the asteroid will briefly peak around apparent magnitude 9 and be near the celestial equator.[5] The asteroid will come to opposition (furthest elongation in the sky from the Sun) on 27 January 2015 at 04:31 UT.[5] The Goldstone Deep Space Network will observe the asteroid during the January 2015 close approach.[6]
