(357439) 2004 BL 86 is an asteroid about 330 meters in size, whose orbit brought it to Earth on January 26, 2015 at 16:20 UTC up to a distance of about one million kilometers. It was discovered on January 30, 2004 as part of a sky surveillance project ( LINEAR ).
The asteroid has its own moon. This was already suspected from earlier optical observation data and was clearly shown on the occasion of the approach to Earth on January 26, 2015 by the radar images of the Goldstone radio telescope at a distance of 1.2 million kilometers. The moon's diameter was determined to be 70 meters.
In the night of January 26th to 27th, 2015 (CET) the asteroid should reach an apparent magnitude of 9.0 mag and between 4:00 and 5:00 UTC pass the star cluster (M44) Praesepe in this brightness . run through.
