Near-Earth Object
523818 (2010 SH13
NASA ID: 20523818
523818 (2010 SH13 will pass Earth on 10 November 2026 at a distance of 154.29 lunar distances (LD) - about 59,309,139 km - travelling at 29,078 km/h. Its estimated diameter is between 148 and 331 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 523818 (2010 SH13 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 523818 (2010 SH13 to Earth between 1941 and 2096, 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 →
