Near-Earth Object
364136 (2006 CJ
NASA ID: 20364136
364136 (2006 CJ will pass Earth on 4 February 2027 at a distance of 64.12 lunar distances (LD) - about 24,648,311 km - travelling at 93,923 km/h. Its estimated diameter is between 245 and 547 metres, roughly the size of Ben Nevis (1,345 m tall). NASA classifies it as a potentially hazardous asteroid (PHA) - a designation based on size and orbital proximity, not on any predicted impact.

The real orbit in 3D
The actual path of 364136 (2006 CJ 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 364136 (2006 CJ to Earth between 1943 and 2081, 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 →
