As well as various other types of wobbles:

So, how common is wobbling? Is everything wiggling and wobbling out there?

I would think that "wobbling" is normal in objects in space in that there are so many gravitational influences around. Many bodies are not actually solid too, as in the Earth's molten interior which has it's independent motion.
