This is a pretty confined definition for a specific class of rock. Often smaller rocks that pose a higher impact risk are also called PHAs. The recurrence interval for a 140m+ impact is thousands of years. The idea is to catalog them all so we can be sure when the next impact might happen.

Rocks that fall under the PHA umbrella from the link above mostly pose no direct threat in the next 100+ years. Their orbits tend to be more gravitationally dynamic though, they can evolve into new orbits which might pose a threat in the future so they get closer attention.

We are a leading near-Earth Object survey operating at the UofA. We'd like to share interesting discoveries with the feed.
