Near-Earth Object
526798 (2007 AA9
NASA ID: 20526798
526798 (2007 AA9 will pass Earth on 3 April 2027 at a distance of 55.58 lunar distances (LD) - about 21,365,142 km - travelling at 35,762 km/h. Its estimated diameter is between 81 and 181 metres, roughly the size of The Shard in London (310 m tall). NASA does not classify it as potentially hazardous.

Every recorded pass
Each dot is one close approach of 526798 (2007 AA9 to Earth between 1928 and 2095, 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 →
