Near-Earth Object
2024 ON2
NASA ID: 54465291
2024 ON2 will pass Earth on 3 August 2026 at a distance of 101.81 lunar distances (LD) - about 39,134,346 km - travelling at 79,449 km/h. Its estimated diameter is between 32 and 71 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 →
