Near-Earth Object
2020 WA3
NASA ID: 54092910
2020 WA3 will pass Earth on 8 August 2027 at a distance of 87.65 lunar distances (LD) - about 33,693,842 km - travelling at 48,270 km/h. Its estimated diameter is between 13 and 29 metres, roughly the size of a double-decker bus (around 11 m long). 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 →
