2025 FM12

NASA ID: 54524985

Safe

2025 FM12 will pass Earth on 19 March 2027 at a distance of 67.88 lunar distances (LD) - about 26,093,590 km - travelling at 42,406 km/h. Its estimated diameter is between 11 and 24 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 →
