9 body systems?

Question

9 body systems?

Answer 1

In no particular order:

Respiratory, Circulatory, Reproductive, Endocrine, Pulmonary, Nervous, Digestive, Skeletal, Muscular

There are other ones as well (lymphatic, immune, etc.) but those are the main ones I would say.

Answer 2

Actually the solar system can be seen as a 10 body system, but now that Pluto has been demoted, it's a 9 body system.

Mathematically, any multi-body system with N>2 is unsolvable.  To solve complicated orbital problems and missions between planets, you have to use large computers to get numerical solutions by approximation methods.

There seems to be a contest to see who can post the question with the least number of words and the least information.

Please!

It may be funny, but it wastes my time and wastes your time, and doesn't get a good answer.

Just type in all the information you have, all the details, and you will get a good answer, instead of a bunch of angry people.
