4486 Mithra (1987 SB)
Tracked by NASA JPL Near-Earth Object Web Service (NeoWs), 4486 Mithra (1987 SB) is a Not published by JPL SBDB body measuring between 1849m and 1849m in diameter. On 2036-07-26, it completes a cislunar approach at 60.62 Lunar Distances (23,301,908 km) with a relative heliocentric velocity of 13.45 km/s.
4486 Mithra (1987 SB) (JPL ID 4486) is a Not published by JPL SBDB Near-Earth Asteroid spanning 1849.0m–1849.0m (mean 1849m). On 2036-07-26, it transits Earth's cislunar surveillance sector at 60.619 Lunar Distances (23,301,908 km) with a relative velocity of 13.45 km/s and a theoretical kinetic energy reserve of 203928.12 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.
