101955 Bennu (1999 RQ36)
Tracked by NASA JPL Near-Earth Object Web Service (NeoWs), 101955 Bennu (1999 RQ36) is a B body measuring between 484.4m and 484.4m in diameter. On 2037-02-11, it completes a cislunar approach at 38.42 Lunar Distances (14,767,318 km) with a relative heliocentric velocity of 7.53 km/s.
101955 Bennu (1999 RQ36) (JPL ID 101955) is a B Near-Earth Asteroid spanning 484.4m–484.4m (mean 484.4m). On 2037-02-11, it transits Earth's cislunar surveillance sector at 38.417 Lunar Distances (14,767,318 km) with a relative velocity of 7.53 km/s and a theoretical kinetic energy reserve of 1149.28 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.
