Near-Earth Object
2022 AB4
NASA ID: 54236436
2022 AB4 will pass Earth on 3 July 2026 at a distance of 156.65 lunar distances (LD) - about 60,217,946 km - travelling at 77,238 km/h. Its estimated diameter is between 12 and 26 metres, roughly the size of a double-decker bus (around 11 m long). NASA does not classify it as potentially hazardous.

The real orbit in 3D
The actual path of 2022 AB4 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 2022 AB4 to Earth between 2022 and 2072, 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 →
