1997 XR2 was discovered on December 4, 1997 by the NASA-founded LINEAR asteroid survey.
This asteroid has led the Impact Risk page since early 2002 to February 2006.
On February 24, 2006, 1997 XR2 was observed by Mt. Lemmon Survey after being lost for more than 8 years. The refinement of its orbit eliminated the possibility of impact in 2101 (sprawdzić)!).
The object is estimated at 200—460 metres.
