Near-Earth Object
2021 YQ
NASA ID: 54231776
2021 YQ will pass Earth on 22 March 2027 at a distance of 81.91 lunar distances (LD) - about 31,485,067 km - travelling at 44,277 km/h. Its estimated diameter is between 46 and 103 metres, roughly the size of a football pitch (around 105 m long). NASA does not classify it as potentially hazardous.

The real orbit in 3D
The actual path of 2021 YQ 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 2021 YQ to Earth between 1956 and 2022, 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 →
