2002 NT7

2002 NT7 is a near-Earth object (NEO) that became the first object observed by NASA's NEO program to be assigned a positive rating on the Palermo Technical Impact Hazard Scale for a potential impact date of February 1 2019. Despite inflammatory press reports, the object has a "low probability" of impact, approximately one in a million.

Further observations of the object have since re-rated the threat lower. As of July 25 2002, the hazard rating on the Palermo scale had been lowered to -0.25. However, the discovery of an object with an initial hazard rating above 0.0 is still a significant event in the history of the NEO observation program.

On August 1 2002, the object was removed from the list of objects that present a threat, at least for the next 100 years.
