2023 QM

NASA ID: 54377188

Safe

2023 QM will pass Earth on 1 September 2026 at a distance of 119.16 lunar distances (LD) - about 45,804,107 km - travelling at 38,817 km/h. Its estimated diameter is between 11 and 26 metres, roughly the size of a double-decker bus (around 11 m long). NASA does not classify it as potentially hazardous.

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 →
