chongo's Journal: 2002-SM asteroid update for 2002-Sep-30 05:30 UTC

New observations came in for the asteroid 2002-SM that refined its orbit model. The new model shows that this object is not a potential Earth impactor in the foreseeable future.

Asteroid 1997-XR2 remains the only asteroid that has a non-zero Torino impact hazard scale value. See my previous journal entry titled 09 Aug 2002 00:00 UTC update for the 1997-XR2 asteroid for more details on 1997-XR2.
