(2020 CB)
Tracked by NASA JPL Near-Earth Object Web Service (NeoWs), (2020 CB) is a Unreported by NASA NeoWs body measuring between 7.67m and 17.14m in diameter. On 2026-10-29, it completes a cislunar approach at 110.97 Lunar Distances (42,675,136 km) with a relative heliocentric velocity of 9.93 km/s.
(2020 CB) (JPL ID 3989355) is a Unreported by NASA NeoWs Near-Earth Asteroid spanning 7.7m–17.1m (mean 12.4m). On 2026-10-29, it transits Earth's cislunar surveillance sector at 110.968 Lunar Distances (42,675,136 km) with a relative velocity of 9.93 km/s and a theoretical kinetic energy reserve of 0.03 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 (2020 CB) compared to city landmarks?
(2020 CB) has an estimated diameter between 7.67m and 17.14m. At its upper-bound size of 17.14m, it stands 4% as tall as the 443m Empire State Building in New York City and 5% of the 330m Eiffel Tower.
What does the stored 2026-10-29 close-approach estimate show?
This catalog snapshot lists a nominal miss distance of 110.97 Lunar Distances (42,675,136 km) for (2020 CB). This is not an impact prediction; check the latest NASA JPL record for updated orbital estimates. The 3D impact simulation is hypothetical.
