<title>Near Earth Objects (NEOs) &  Potentially Hazardous Asteroids (PHAs)</title>
===== Introduction =====
Some intro reading materials about NEOs and PHAs.

  * [[https://cneos.jpl.nasa.gov/|CNEOS]]
    * Read "NEO Basics"
    * There are other useful info in this website including: (1) NEO orbit into, (2) impact risk, (3) discovery statistics, (4) recent flybys ("fireballs"), and (5) other (potentially technical) documents.
