2023 SP2

NASA ID: 54385785

Safe

2023 SP2 will pass Earth on 3 October 2026 at a distance of 43.09 lunar distances (LD) - about 16,564,860 km - travelling at 12,682 km/h. Its estimated diameter is between 6 and 13 metres, roughly the size of a double-decker bus (around 11 m long). NASA does not classify it as potentially hazardous.

The real orbit in 3D

The actual path of 2023 SP2 around the Sun, computed from JPL orbital elements. Drag to rotate, scroll to zoom, and use the time controls to run the orbit forwards or back.

Every recorded pass

Each dot is one close approach of 2023 SP2 to Earth between 1914 and 2040, 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 →
