Near-Earth Object
478784 (2012 UV136
NASA ID: 20478784
478784 (2012 UV136 will pass Earth on 10 June 2027 at a distance of 193.08 lunar distances (LD) - about 74,219,668 km - travelling at 66,437 km/h. Its estimated diameter is between 20 and 45 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 478784 (2012 UV136 to Earth between 1952 and 2099, 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.
Size Comparison
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 →
