Near-Earth Object
456938 (2007 YV56
NASA ID: 20456938
456938 (2007 YV56 will pass Earth on 28 June 2027 at a distance of 19.59 lunar distances (LD) - about 7,530,191 km - travelling at 64,037 km/h. Its estimated diameter is between 169 and 378 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 456938 (2007 YV56 to Earth between 1927 and 2029, 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 →
