3200 Phaethon (1983 TB)
Tracked by NASA JPL Near-Earth Object Web Service (NeoWs), 3200 Phaethon (1983 TB) is a B / F body measuring between 6250m and 6250m in diameter. On 2050-12-11, it completes a cislunar approach at 32.14 Lunar Distances (12,353,117 km) with a relative heliocentric velocity of 36.24 km/s.
3200 Phaethon (1983 TB) (JPL ID 3200) is a B / F Near-Earth Asteroid spanning 6250.0m–6250.0m (mean 6250m). On 2050-12-11, it transits Earth's cislunar surveillance sector at 32.136 Lunar Distances (12,353,117 km) with a relative velocity of 36.24 km/s and a theoretical kinetic energy reserve of 57179221.86 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.
