Near-Earth Object
453707 (2010 XY72
NASA ID: 20453707
453707 (2010 XY72 will pass Earth on 29 October 2027 at a distance of 18.68 lunar distances (LD) - about 7,180,470 km - travelling at 64,903 km/h. Its estimated diameter is between 495 and 495 metres, roughly the size of The Shard in London (310 m tall). NASA classifies it as a potentially hazardous asteroid (PHA) - a designation based on size and orbital proximity, not on any predicted impact.

Every recorded pass
Each dot is one close approach of 453707 (2010 XY72 to Earth between 1916 and 2068, 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 →
