NEOs: Near Earth Objects, or Nasty Existential Obliteration

President-Elect, take note of the large number of Near Earth Objects, and our current inability to track them all effectively, let alone deal effectively with one on a collision course:

The numbers here are stark. NASA’s Near Earth Object Program reports that we’ve found 5,955 NEOs, some 763 of which are at least one kilometer in diameter. 1008 NEOs larger than 140 meters across come within 4.5 million miles of Earth’s orbit, dangerous to us because perturbing influences could change their trajectories in the future. Centauri Dreams believes that the discovery of an object on a collision course with Earth would galvanize the space program as researchers looked for the best ways to deflect its path. The problem is time.

As existential risks go, a meteor strike is rather different to the others – statistically less likely to happen (or so we hope), but fast and utterly devastating of it does. Keep watching the skies, people… [image by larkspurlazuli]
