NEO's are regularly discussed in the scientific and regular media.

Currently, no object is rating above zero on the Torino scale of impact risk. There have been times of excitement when this has not been the case, but every time something rated higher, more detailed investigation showedthe risk was not imminent.

The issue of NEO's IS a real one, but must be tackled rationally. The timescales and risks are huge, and hard to understand, but we need to keep a better eye on things than the Dinosaurs did!
