2021 TO8

NASA ID: 54206544

Safe

2021 TO8 will pass Earth on 6 October 2026 at a distance of 103.55 lunar distances (LD) - about 39,803,220 km - travelling at 51,379 km/h. Its estimated diameter is between 7 and 16 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 2021 TO8 to Earth between 1910 and 2074, 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 →
