[Vo]:Asteroid 2009 DD45

[Horace Heffner]

Asteroid 2009 DD45 had a 48,000 mile close call March 2, 2009.  What  
has not explicitly been said AFAIK is whether or not that was within  
a window that can establish a "resonant return", i.e. a direct hit on  
a return fly by.  Perhaps it is too soon to know due to the near  
earth gravitational anomalies.

Best regards,
