Paul Chodas & Jon Giorgini- NASA/JPL Near-Earth Object Program Office January 22, 2015
This 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. ...
