Near-Earth Object
2022 SW20
NASA ID: 54309248
2022 SW20 will pass Earth on 22 September 2026 at a distance of 49.91 lunar distances (LD) - about 19,184,162 km - travelling at 65,989 km/h. Its estimated diameter is between 13 and 30 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 SW20 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 SW20 to Earth between 1936 and 2064, 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 →
