It's a bouncing meatball...

“Bennu’s rotation rate is speeding up over time — by about 1 second each century.”

Measurement error.

That’s my thought too.

Is it spinning right or left? In particle physics this creates different attributes.

Funny how right after we are absolutely sure about something, we find out we were wrong.

Outside forces: gravity, solar wind, something (unknown, not visible particles) are hitting it.

Could simply be "outgassing" something.

Like a rocket, it moves off in the opposite direction.

If there is outgassing from inside the rock it would cause the rotation to quicken. Because an ordinary spinning object in space should continue spinning at the same rate, unless an outside force acts upon it.

Its radius must be shrinking. Asteroid becoming denser over time?

I don't think the rock is massive enough to contract under its own gravitation. But I of course could be wrong.

One second a century is not much compression. It must be a solid piece of rock or iron or something. If it is loose particles there wouldn’t be enough gravity to keep it together, as you say.

That would be my thought, but I don’t see how a solid piece of rock or iron or whatever would compress over time.

“Measurement error.”

My thinking, too. At 1 second each century it would have to be observed a looooong time to say if it’s speeding up, slowing down or no change at all.

It increases speed with each lie Hillary tells?

(just a theory)
