Potentially Hazardous Asteroid
4015 Wilson-Harrington (1979 VA) is classified as a Potentially Hazardous Asteroid (PHA) because it is estimated to be larger than 140 meters and its orbit comes within 0.05 AU of Earth. NASA continuously monitors this object for any future impact risk. Current data does not indicate a confirmed impact event.
Periodic comet with 4 year orbit
4015 Wilson–Harrington is an active asteroid known both as comet 107P/Wilson–Harrington and as asteroid 4015 Wilson–Harrington. It passed 0.4 AU (60 million km) from Earth on 20 July 2022 and then passed perihelion on 24 August 2022. It seldom gets brighter than apparent magnitude 16. It will return to perihelion on 25 November 2026.
