4015 Wilson-Harrington (1979 VA)
Tracked by NASA JPL Near-Earth Object Web Service (NeoWs), 4015 Wilson-Harrington (1979 VA) is a CF body measuring between 4000m and 4000m in diameter. On 2039-10-31, it completes a cislunar approach at 42.14 Lunar Distances (16,200,077 km) with a relative heliocentric velocity of 12.13 km/s.
4015 Wilson-Harrington (1979 VA) (JPL ID 4015) is a CF Near-Earth Asteroid spanning 4000.0m–4000.0m (mean 4000m). On 2039-10-31, it transits Earth's cislunar surveillance sector at 42.144 Lunar Distances (16,200,077 km) with a relative velocity of 12.13 km/s and a theoretical kinetic energy reserve of 1679281.05 megatons TNT. Classified as a Potentially Hazardous Asteroid (PHA) due to its Minimum Orbit Intersection Distance (MOID <= 0.05 AU) and absolute magnitude (H <= 22.0), it remains under high-priority radar and optical astrometric tracking.
