"Nutation" is a "wobbly" spin motion.

In Latin Nutatio,-onis means "decay".
The word is part of the jargon used in astronomy, and spacecraft dynamics.

A perfect spin motion can degenerate into nutation when a certain kind of dynamic "unbalance" takes place. If left alone, it becomes a very serious spacecraft problem.
