Near-Earth Object
217628 Lugh (1990 HA
NASA ID: 20217628
217628 Lugh (1990 HA will pass Earth on 28 November 2026 at a distance of 27.54 lunar distances (LD) - about 10,586,578 km - travelling at 63,753 km/h. Its estimated diameter is between 1,400 and 1,400 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 217628 Lugh (1990 HA 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 217628 Lugh (1990 HA to Earth between 1985 and 2084, 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 →
