4179 Toutatis (1989 AC)
Tracked by NASA JPL Near-Earth Object Web Service (NeoWs), 4179 Toutatis (1989 AC) is a Sk body measuring between 5400m and 5400m in diameter. On 2069-11-05, it completes a cislunar approach at 7.72 Lunar Distances (2,969,321 km) with a relative heliocentric velocity of 8.41 km/s.
4179 Toutatis (1989 AC) (JPL ID 4179) is a Sk Near-Earth Asteroid spanning 5400.0m–5400.0m (mean 5400m). On 2069-11-05, it transits Earth's cislunar surveillance sector at 7.725 Lunar Distances (2,969,321 km) with a relative velocity of 8.41 km/s and a theoretical kinetic energy reserve of 1986072.43 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.
