Mr. Bratch. Oh Mr. Bratch! That lady ...
That pitcher of that lady. Um, uh. She, uh ...
Uhhhhhhhh, golly! Gee whiz.
She, um, that pitcher makes me feel funny.
Down there. You know where! Uh huh. Uh oh!
Down in my “Danger Zone”.
Yo why should we break up if we keep making up?
I mean lets just stay together..
Uhhh. eh yeah...

For asteroids about 100 meters [328 feet] in diameter collisions are not the primarily cause of break ups -- rapid rotation is," the Smithsonian Astrophysical Observatory stated. Moreover, because the rate of collisions depends on the numbers and sizes of objects but rotation does not, their results are in strong disagreement with previous models of collisionally-produced small asteroids.IOW, small bodies acquire spin directly or indirectly through solar energy, and fly apart. Of course, this doesn't explain the fact that asteroids studied up close appear to be made up of at least several smaller bodies in the first place. :')
A Mathematician, a Physicist, and an astronomer were traveling north by train. They had just crossed the border into Scotland, when the Astronomer looked out of the window and saw a single black sheep in the middle of a field. "All Scottish sheep are black," he remarked."No, my friend," replied the Physicist, "Some Scottish sheep are black."
At which point the Mathematician looked up from his paper and glanced out the window. After a few second's thought he said blandly: "In Scotland, there exists at least one field, in which there exists at least one sheep, at least one side of which is black."

Um, and that rotation began how?
My asteroids broke up all by themselves - didn’t even need Preparation H. But they weren’t astronomically large.
I have long proposed that if we detect a “killer” asteroid that is going to strike the Earth at some time in the future, that rapid spinning could be used to remove the threat. This would be accomplished by landing several small ion engines on the asteroid in a pattern designed to rotate the asteroid. Rotate it enough and you can alter the trajectory. Rotate it even faster and you can spin it apart.
I thought they broke up when you nuked them. But now we need to launch a planet size robot to spin them rapidly.
I’m going to reserve judgement until I hear the Taylor Swift song. Nobody captures breakups as well as she does.
A lot of asteroids have “moons”, smaller bodies orbiting, which would seem to indicate they are massive enough to be gravitationally bonded. Saturn’s moonlets embedded in its rings are held together by tensile strength, tidal forces are not strong enough to tear them apart.
Clearly, anything outside the orbit of Mercury is outside the Sun’s “Roche Limit”, meaning that gravitationally bound bodies can form, orbitally induced tides are smaller than gravity. A particle is gravitationally bound to a larger body if the gravitational force is greater than the centripetal force. Spin anything fast enough and it will fly apart.

LOL. Who’s on first?
