Near-Earth Object
452302 (1995 YR1
NASA ID: 20452302
452302 (1995 YR1 will pass Earth on 8 January 2027 at a distance of 142.37 lunar distances (LD) - about 54,726,434 km - travelling at 67,485 km/h. Its estimated diameter is between 239 and 535 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 452302 (1995 YR1 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 452302 (1995 YR1 to Earth between 1942 and 2077, 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 →
