    Nominal orbit of 2001 WN5 (green line) passing the Earth–Moon system in June 2028

    It was discovered by the Lowell Observatory Near-Earth-Object Search at Anderson Mesa Station on 20 November 2001, [4] The potentially hazardous asteroid was removed from the Sentry Risk Table on 30 January 2002. [5]

    There are precovery images dating back to 10 February 1996. [1] The orbit is well determined with an observation arc of 14.9 years which includes two radar delay observations. It has an Uncertainty Parameter of 0. [1]

    The asteroid will pass 248,700 km (0.647 LD) from the Earth on 26 June 2028. [1] During the close approach, the asteroid should peak at about apparent magnitude 6.7, [6] and will be visible in binoculars. It has an absolute magnitude (H) of 18.2. [1]

    According to observations by the NEOWISE mission, the asteroid measures approximately 0.9 km in diameter and its surface has a rather low albedo of 0.097. [2]
