Near-Earth Object
2023 CK
NASA ID: 54340798
2023 CK will pass Earth on 16 November 2026 at a distance of 160.81 lunar distances (LD) - about 61,813,901 km - travelling at 77,039 km/h. Its estimated diameter is between 10 and 23 metres, roughly the size of a double-decker bus (around 11 m long). NASA does not classify it as potentially hazardous.

Size Comparison
Reading the Numbers
- A lunar distance (LD) is the average gap between Earth and the Moon, about 384,400 km. It is the standard yardstick for close approaches. Read more →
- Diameter estimates come from brightness. A dark surface reflects less light than a bright one, so the true size can sit anywhere in the quoted range. Read more →
- Potentially hazardous is a watch-list label based on size and orbital proximity. It does not mean an impact is expected. Read more →
