If the U.S. Air Force and NASA have anything to say about it, never.
There are probably a hundred thousand comets out in space that we've never seen because the LAST time they approached the Sun was before man existed, or had invented writing; in either event, we have no record of it. Sooner or later, a comet will fall into the solar system on a collision course with the Earth. We know this WILL happen - we just don't know WHEN.
So scientists are slowly working out ways to intercept or deflect or destroy such a comet.
It probably won't happen for a thousand years or more. But the Earth is about 4 billion years old, and will probably exist for that much more. The Earth has been hit many times before. It WILL happen again. We need to start preparing now.
What else can I help you with?

How likely is it for a comet to hit Earth in this lifetime?
Quite low. Debris shed from comets as they orbit the Sun strike the Earth thousands of times per year, but most of the debris, in the form of periodic meteor showers, is pretty tiny; an average sized particle would be the size of a grain of rice or smaller. But for the Earth to be struck by the nucleus of the comet itself? We're not certain that an actual comet has EVER struck the Earth, although we can be relatively confident that objects about the size of a comet has hit the Earth once every few thousand years or so. The probability of a comet striking the Earth within the next 50 years is quite low; one or two percent, but no higher.
How much space would a comet wipe out if it hit Earth?
Depends on how big the Comet is.
