That's just the attitude control system. Impact isn't for another five years.

It's speeding up in it's rotation gradually, by 4ms a year.

Isn't it save to assume the asteroid either loses mass, or it's mass is somehow pulled towards the center? And if it's pulled towards the center, isn't a possible explanation that it has a liquid core, since rotating liquids pull mass towards the center?
