Isn't it possible for a peice of the Dumbell Size Asteroid coming apart striking earth? who knows maybe it will strike Mecca?
I vote for a large breakup and impact on Mecca, Medina, the Kaaba, Riyadh, Tehran, Falluja, Najaf, Damascas, the eastern part of Ottawa...and PARIS!
Astronomers know of no such impending doom.
If they did, do you suppose they would tell us?
Even if the asteroid split (called calving), the two pieces would continue in the same orbit unless one of them was influenced by an external force.
Other than tidal forces, I do not see this as a threat. BTW, this object is too small (short) to split via tidal forces.
Oh, sure, look on the bright side. ;')
