OT: Ceres more interesting than previously thought

[Suicide Junkie]

Reducing spin DOES NOT decrease the gravity by any measureable amount.
The rate at which you add mass means absolutely nothing.

The spin-rockets would have to be landed on the surface carefully, which means matching the spin rate of the surface so as not to plow into the asteroid and leave a crater full of expensive shrapnel. Installing the rockets would not change the spin rate of Ceres, and would increase its mass and angular momentum by an unnoticable fraction.

Unfortunately, searching for '"Ning Li" site:ua.edu' turns up zero items.
Ning and Li appear separately, though, as different people.

And if you open it to non - University of Alabama sites relating to spin and gravity, you get a buttload of crackpots, alien/UFO sites and such.

I'm sorry, but Newton's laws are the way it is, to great precision on the scales we are talking about.

Again, this is simple grade 9 physics.
Learn the basics, please.
