Near-Earth Object
886662 (2021 JY
NASA ID: 20886662
886662 (2021 JY will pass Earth on 26 April 2027 at a distance of 58.03 lunar distances (LD) - about 22,305,514 km - travelling at 83,645 km/h. Its estimated diameter is between 462 and 1,033 metres, roughly the size of Ben Nevis (1,345 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 actual path of 886662 (2021 JY 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 886662 (2021 JY to Earth between 2002 and 2004, 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 →
