Near-Earth Object
756065 (2018 DH1
NASA ID: 20756065
756065 (2018 DH1 will pass Earth on 18 July 2027 at a distance of 22.1 lunar distances (LD) - about 8,493,767 km - travelling at 45,544 km/h. Its estimated diameter is between 157 and 352 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 756065 (2018 DH1 to Earth between 1900 and 2027, 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 →
