Near-Earth Object
2023 CK2
NASA ID: 54341550
2023 CK2 will pass Earth on 4 March 2027 at a distance of 179.57 lunar distances (LD) - about 69,027,698 km - travelling at 105,840 km/h. Its estimated diameter is between 77 and 173 metres, roughly the size of The Shard in London (310 m tall). 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 →
