Planetary Defense Frequently Asked Questions (Schema.org FAQ)
How big is (2018 GS1) compared to city landmarks?
(2018 GS1) has an estimated diameter between 80.64m and 180.32m. At its upper-bound size of 180.32m, it stands 41% as tall as the 443m Empire State Building in New York City and 55% 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 11.03 Lunar Distances (4,240,878 km) for (2018 GS1). This is not an impact prediction; check the latest NASA JPL record for updated orbital estimates. The 3D impact simulation is hypothetical.
