Updated Uncertainty Region for 2007 WD5 at encounter with Mars, shown as white dots. The thin white line is the orbit of Mars. The blue line traces the motion of the center of the uncertainty region, which is the most likely position of the asteroid. Note that the scale is considerably finer than it has been in past diagrams.by Don Yeomans, Paul Chodas and Steve Chesley Pasadena CA (JPL)
