Near-Earth Object
2024 YP9
NASA ID: 54512606
2024 YP9 will pass Earth on 3 December 2026 at a distance of 29.01 lunar distances (LD) - about 11,151,054 km - travelling at 20,246 km/h. Its estimated diameter is between 90 and 201 metres, roughly the size of The Shard in London (310 m tall). NASA does not classify it as potentially hazardous.

The real orbit in 3D
The actual path of 2024 YP9 around the Sun, computed from JPL orbital elements. Drag to rotate, scroll to zoom, and use the time controls to run the orbit forwards or back.
Every recorded pass
Each dot is one close approach of 2024 YP9 to Earth between 1909 and 2066, from JPL's records. Lower means closer: a dot under the dashed line passed nearer than the Moon. The orange dot is the approach on this page.
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 →
