Close-Approach Date: 2011-Jun-02 about 1am UTC

Miss Distance, the most likely possible miss distance given in LD (Lunar Distance) and AU:
0.9LD 0.0023AU

V relative, Object velocity relative to Earth at close-approach: 1.91 (on the slow side)

N-sig, The factor by which the target-plane error ellipse must be scaled to allow for an Earth grazing impact: 4.17e+04

H, Asteroid absolute V-magnitude: 28.3 (near average)

Will pass within ~346,000 kilometers (using an average LD value). That is also the closest pass of all known calculated NEOs for the next year. Somewhat rare.

Still, not exactly at close call.
