612356 (2002 JX8

NASA ID: 20612356

⚠ Hazardous

612356 (2002 JX8 will pass Earth on 15 April 2027 at a distance of 48.73 lunar distances (LD) - about 18,730,342 km - travelling at 30,830 km/h. Its estimated diameter is between 267 and 597 metres, roughly the size of Ben Nevis (1,345 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 612356 (2002 JX8 to Earth between 1906 and 2092, 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.

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 →
