    • I'll leave this with the folks who have done all the work on this article. The use of "unprecedented" in the second paragraph does not make sense. 1. This is big enough to cause unprecedentedregional devastation... once per 10,000 years I would suggest simply removing the word would be better than trying to dress up the statement with unnecessary a...

      This is a list of examples where an asteroid or meteoroid travels close to the Earth. Some are regarded as potentially hazardous objects if they are estimated to be large enough to cause regional devastation. Near-Earth object detection technology began to improve around 1998, so objects being detected as of 2004 could have been missed only a decade earlier due to a lack …

      A near-Earth object (NEO) is any small Solar System body whose orbit brings it into proximity with Earth.By convention, a Solar System body is a NEO if its closest approach to the Sun is less than 1.3 astronomical units (AU).If a NEO's orbit crosses the Earth's orbit, and the object is larger than 140 meters (460 ft) across, it is considered a potentially hazardous object (PHO).
