Near-Earth Object
250680 (2005 QC5
NASA ID: 20250680
250680 (2005 QC5 will pass Earth on 9 July 2026 at a distance of 79.27 lunar distances (LD) - about 30,472,665 km - travelling at 54,708 km/h. Its estimated diameter is between 398 and 398 metres, roughly the size of The Shard in London (310 m tall). NASA classifies it as a potentially hazardous asteroid (PHA) - a designation based on size and orbital proximity, not on any predicted impact.

The real orbit in 3D
The actual path of 250680 (2005 QC5 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 250680 (2005 QC5 to Earth between 1924 and 2092, 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 →
