An asteroid
As far as we know there is not a asteroid headed for mars. but there might be actually, there's no evidence to prove the answer.
Gravity
There might a possibility but were still not sure.
It's a question of sufficient gravity. A man might walk right off the asteroid if he tried to walk at all.
An asteroid might hit at any moment. There is no reason to believe that an asteroid will hit any time soon, though.
Most likely it would just shatter it into smaller asteroids, which might do more total damage than the original asteroid.
It's an asteroid and only an asteroid. A big one at that, second to Ceres (Dwarf Planet) and there is a possibility that it might be added to dwarf planet status in the near future once it's shape has been confirmed.
