(2019 SE9)
Tracked by NASA JPL Near-Earth Object Web Service (NeoWs), (2019 SE9) is a Unreported by NASA NeoWs body measuring between 24.69m and 55.21m in diameter. On 2026-10-28, it completes a cislunar approach at 152.08 Lunar Distances (58,487,173.2 km) with a relative heliocentric velocity of 14.69 km/s.
(2019 SE9) (JPL ID 3873149) is a Unreported by NASA NeoWs Near-Earth Asteroid spanning 24.7m–55.2m (mean 40m). On 2026-10-28, it transits Earth's cislunar surveillance sector at 152.084 Lunar Distances (58,487,173 km) with a relative velocity of 14.69 km/s and a theoretical kinetic energy reserve of 2.46 megatons TNT. Its well-constrained heliocentric ephemeris passes safely outside Earth capture corridors while serving as an orbital calibration target.

Planetary Defense Frequently Asked Questions (Schema.org FAQ)
How big is (2019 SE9) compared to city landmarks?
(2019 SE9) has an estimated diameter between 24.69m and 55.21m. At its upper-bound size of 55.21m, it stands 12% as tall as the 443m Empire State Building in New York City and 17% of the 330m Eiffel Tower.
What does the stored 2026-10-28 close-approach estimate show?
This catalog snapshot lists a nominal miss distance of 152.08 Lunar Distances (58,487,173.2 km) for (2019 SE9). This is not an impact prediction; check the latest NASA JPL record for updated orbital estimates. The 3D impact simulation is hypothetical.
