6489 Golevka (1991 JX)
Tracked by NASA JPL Near-Earth Object Web Service (NeoWs), 6489 Golevka (1991 JX) is a Q body measuring between 530m and 530m in diameter. On 2046-05-14, it completes a cislunar approach at 19.77 Lunar Distances (7,600,023 km) with a relative heliocentric velocity of 13.41 km/s.
6489 Golevka (1991 JX) (JPL ID 6489) is a Q Near-Earth Asteroid spanning 530.0m–530.0m (mean 530m). On 2046-05-14, it transits Earth's cislunar surveillance sector at 19.771 Lunar Distances (7,600,023 km) with a relative velocity of 13.41 km/s and a theoretical kinetic energy reserve of 4774.27 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.
