When will the next big asteroid strike Earth?

Nobody knows, but don’t lose any sleep over the thought of a space rock landing in your living room. Several monitoring projects – such as Spacewatch and the Minor Planet Center – use powerful telescopes to scan the skies and track the courses of any “near-Earth objects,” including asteroids that might drift too close to home. NASA has identified 90 percent of all the near-Earth objects large enough to cause catastrophic damage if they stuck our planet. So far, we’re in the clear.
