[William Tell]

I knew off the top of my head that Jupiter revolves around the sun about every 11 years.

I also knew that the sunspot cycles seemed to repeat about every 11 years.

I feel like an idiot for not making the connection. How can this be news? Are our scientists too busy trying to earn federal grants?

It is unlikely. Jupiter’s orbital period is 11.86 years, whereas the sunspot cycle averages out to 11.05 years. And the sunspots are actually representative of variations in the Sun’s magnetic field, which because it changes in polarity actually has a full cycle of 22 years.

It is also believed to be generated by events deep in the Sun, so it is difficult to conceive of any physical force from Jupiter that would be strong enough to drive it.
