Anybody know how close Mars moons orbit? Those distances would be well within the orbit of our moon.
There may be a possibility of that the asteroid will strike one of Mars moons.
Of the two, Deimos is more likely to be a potential target. However, something that small would be like putting your wife on a merry-go-round with a lit cigarette in her mouth and attemtping to shoot off the cherry at 500 yards with an AK. :)
