Some interesting information from the UN
Hear are some highlightes
"We currently know of and are tracking about 3,000 NEOs of a size capable of
destroying a major city on impact. Within the next 10-15 years we will be tracking the
orbits of over 300,000 such objects. Based on current data 97% of these objects will
have no chance of impact over the next century. However of the remaining 3% there
are likely to be many that will appear threatening enough to seriously consider
deflection."
"It should be emphasized that the opening question the political community will ask is
whether or not the threat of NEO impacts is a real issue and whether it needs to be
dealt with now. The ASE believes the proper answers to these questions are “yes” and
“yes,” and it is the basis on which we believe this to be true that the presentation and
discussion will be based. It is not therefore the recommendations we will be making to
the UN which are at issue now, but rather whether being prepared to deal with NEO
impact threats is ripe for their consideration."

How do you deflect one of these, one possibility NASA investigated-

A Gravity tractor (GT) is a spacecraft that deflects another object in space, typically a potentially hazardous asteroid that might impact Earth, without physically contacting it, using only its gravitational field to transmit the required impulse.[1][2] The tractor spacecraft could either hover near the object being deflected or orbit near it. The concept has the advantage that essentially nothing need be known about the mechanical composition and structure of the asteroid in advance.
