Star Chart for Asteroid 2004 BL86 Earth Flyby on Jan 26, 2015
The orbit diagram shows the close passage of 2004 BL86 on January 26, 2015. The view is nearly edge-on to the Earth's orbit; the Moon's nearly circular orbit is highly foreshortened from this viewpoint. The asteroid moves from the south to the north, from below the Earth's orbit to above. The indicated times are Universal Time. Closest approach occurs at about 16:19 UTC, or about 11:19 EST. The roughly 500-meter (1500-foot) asteroid approaches to within 1.2 million kilometers (750,000 miles) of Earth, or about 3.1 times the distance of the Moon.

The star chart, sky chart shows the two-day track of 2004 BL86 relative to a local horizon at 9 pm in the evening, as seen from locations in the contiguous United States. On the evening of January 26, the asteroid will pass near a brightly shining Jupiter in the eastern sky, about 11 degrees higher relative to the eastern horizon. Cardinal directions are given along the bottom. The times given on the asteroid track are in Universal Time; subtract 5 hours to obtain Eastern Standard Time (EST), 6 hours for CST, 8 hours for PST.
