Near-Earth Object
2024 JY
NASA ID: 54439430
2024 JY will pass Earth on 14 May 2027 at a distance of 100.04 lunar distances (LD) - about 38,453,965 km - travelling at 80,799 km/h. Its estimated diameter is between 22 and 50 metres, roughly the size of a football pitch (around 105 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 →
