6178 (1986 DA)
Tracked by NASA JPL Near-Earth Object Web Service (NeoWs), 6178 (1986 DA) is a Not published by JPL SBDB body measuring between 2300m and 2300m in diameter. On 2038-04-07, it completes a cislunar approach at 77.07 Lunar Distances (29,624,429 km) with a relative heliocentric velocity of 4.86 km/s.
6178 (1986 DA) (JPL ID 6178) is a Not published by JPL SBDB Near-Earth Asteroid spanning 2300.0m–2300.0m (mean 2300m). On 2038-04-07, it transits Earth's cislunar surveillance sector at 77.067 Lunar Distances (29,624,429 km) with a relative velocity of 4.86 km/s and a theoretical kinetic energy reserve of 51248.11 megatons TNT. Its well-constrained heliocentric ephemeris passes safely outside Earth capture corridors while serving as an orbital calibration target.
