(153814) 2001 WN5 is a near-Earth asteroid of the Apollo group. It was first discovered by the LONEOS Project at Anderson Mesa on November 20, 2001, and was later classified as a Potentially Hazardous Asteroid (PHA). It was removed from the Sentry Risk Table on January 30, 2002. There are precovery images dating back to February 10, 1996. The orbit is well determined with an observation arc of 14.9 years using two radar delay observations, and has an Uncertainty Parameter of 0. The asteroid will pass within 250,000 km (0.65 lunar distances) from the Earth on June 26, 2028. During the close approach, the asteroid should peak at about apparent magnitude 6.7, and will be visible in binoculars. It has an absolute magnitude (H) of 18.2. Depending on its characteristics and albedo, it is estimated to be 700 to 1,500 meters in diameter.
