2023 SU5

NASA ID: 54387148

Safe

2023 SU5 will pass Earth on 9 May 2027 at a distance of 150.71 lunar distances (LD) - about 57,934,448 km - travelling at 46,306 km/h. Its estimated diameter is between 50 and 113 metres, roughly the size of a football pitch (around 105 m long). NASA does not classify it as potentially hazardous.

Every recorded pass

Each dot is one close approach of 2023 SU5 to Earth between 1991 and 2069, 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 →
