2022 EF1

NASA ID: 54248963

Safe

2022 EF1 will pass Earth on 4 March 2027 at a distance of 3.51 lunar distances (LD) - about 1,350,187 km - travelling at 37,428 km/h. Its estimated diameter is between 4 and 10 metres, roughly the size of a double-decker bus (around 11 m long). NASA does not classify it as potentially hazardous.

Every recorded pass

Each dot is one close approach of 2022 EF1 to Earth between 1983 and 2027, 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 →
