This asteroid has been in both the Risk List[2] of the European Space Agency (ESA) - Space Situational Awareness (SSA) and in the Sentry List[8] of the Jet Propulsion Laboratory (JPL) - Center for Near Earth Object Studies (CNEOS). On 21 July 2021, this object was removed from the Sentry List,[9] where it was previously listed with the highest Palermo Technical Impact Hazard Scale value due to a possible close encounter with Earth on 5 September 2024.[10]
On 28 February 2122, 2016 NL56 will make its closest encounter with Earth at a nominal distance of 1,710,000 kilometers (0.01144 AU). Two hours later, it will pass the Moon at a nominal distance of 1,320,000 kilometers (0.00885 AU).[11] On 11 May 2148, the asteroid will also approach Mars at a nominal distance of 3,460,000 kilometers (0.02316 AU).[11]
