(89959) 2002 NT7 (provisional designation 2002 NT7) is a near-Earth object with a diameter of 1.4 kilometers and potentially hazardous asteroid of the Apollo group.[2][3] It has a well determined orbit with an observation arc of 64 years including precovery images by Palomar Observatory dating back to 1954.[3]
2002 NT7 became the first object observed by NASA's NEO program to be assigned a positive rating on both the Torino Scale and the Palermo Technical Impact Hazard Scale[5] for a small chance of an impact on 1 February 2019, although it has now been known for years that it would pass Earth at roughly 0.4078 AU (61,010,000 km; 37,910,000 mi) on 13 January 2019 with an uncertainty region of around ±108 km.[6]
