Near-Earth Object
2023 XB1
NASA ID: 54413270
2023 XB1 will pass Earth on 28 September 2026 at a distance of 97.19 lunar distances (LD) - about 37,357,948 km - travelling at 47,595 km/h. Its estimated diameter is between 85 and 190 metres, roughly the size of The Shard in London (310 m tall). NASA does not classify it as potentially hazardous.

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 →
