(89959) 2002 NT7 (also written (89959) 2002 NT7) is a near-Earth object (NEO) with a diameter of 1.2 miles[1] (2 kilometers) 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 on 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 Palermo hazard rating of 0.06[2] was a significant event in the history of the NEO observation program.
2002 NT7 was removed from the Sentry Risk Table on August 1, 2002.[3]
It is now known that on 2019-Jan-13 the asteroid will safely pass 0.4078 AU (61,010,000 km; 37,910,000 mi) from the Earth.[4]
On 2020-Jan-30 the asteroid will pass 0.02718 AU (4,066,000 km; 2,527,000 mi) from 2 Pallas.[5]
