Yeah...its a shame because some people are called thingy and can't use their name here!! girl thingy Galore doesn't seem to have a problem. (at least in preview mode) So I guess we can't even talk about cute little girl thingy cats???

To get back to the center of mass issue as the word for it when applied to orbiting bodies either creates interest in some fora or gets you warned in others (never really understood why). Astronomers have long detected stars that have planets by their 'wobble' they do not appear stationary due to the attraction of the orbiting mass of their planets. It appears that in some people's heliocentric universe this wobble only applies to other mere stars and not to (genuflect) the Sun. If it did then all the planets would display a similar and matching wobble and the distance to the Sun has been measured and nothing changes......
Ever watched someone who flies 'control line' model aircraft leaning back so that their center of mass is still over their feet so they are not pulled over and 'wobbling' around due to the mass of the aircraft 'orbiting' them. The control line does not change length despite the 'wobble'. Even those brave hobbyists who fly two aircraft whose center of mass is a mix of the 3 bodies now - the control lines do not change length despite the hobbyist wobbling.
Just a little mind game - is the model aircraft orbiting the feet of the hobbyist the joint center of mass, or the center of mass of the body of the hobbyist alone?
(And yes I was tempted to call the hobbyist Barry)

Better impanel a UN committee on that!

I would assume that like the Doppler Wobble, the orbits of all the planets in a solar system have a Heliocentric Wobble reflective of the Doppler Wobble.
It stands to reason that if the orbit of Jupiter has a large effect on the Doppler Wobble (orbit) of the Sun, it would have an effect on Earth and other planet's orbits also. Specifically, the gaseous giants in general affecting these other orbits. Not only the planets, but also the Heliosphere/electromagnetic radiation/mass itself.
If the the orbit of the Earth strays to the outer edge of the Goldilock's Zone (.95 to 1.01 AU) in which we reside, one could assume that the Earth would cool and vice versa. It appears that were on the outer edge of the zone though. I would think that we're in a lot more danger of cooling than warming. If the Doppler Wobble varies from 0.1 to 2.2 radii(865,000+ miles)and Earth is 930,000 miles from the edge of the Habitable Zone, it might get really cold if these coincide.
Would this Heliocentric Wobble also affect the shape of the Goldilock's Zone?
Or, it could be caused by something that makes up 0.04% of the atmosphere. Who knows?
I wonder if Astromet has any info showing the positions of Earth relative to the positions of the Sun in different, critical years of the approaching cooling. 2018 for example. 2022.
Just a thought,
juan

More interesting is the effect of the 'doppler wobble' on the various fluid parts of the planets. So the Earth's liquid core, the oceans and the atmosphere. All have varying inertia and the liquid core could also affect the comparatively thin skin we call the crust. Think of the forces required to alter the orbital acceleration of a planet so that it follows a doppler wobble.
But of course I am dreaming - I am repeatedly assured that there is no such thing as orbiting a center of mass.

I think tho when it comes down to it....the planets are too far away and the sun too big for there to be a big effect. So the debate becomes, is this effect big enough to affect anything?? I would have thought there'd be calculations to work this out but theres enough people out there far cleverer then me who cant agree, so i guess its not that simple!!! I like the idea and it 'feels' right, someone should really get a definitive answer, do a phd on it or summat...

How much force is required to change the orbit of the Earth and Jupiter as the barycenter moves? How much force is required to 'wobble' the Sun?

Its hard to believe some of the things you read but, I remember reading that 27% of people globally think that the Sun orbits the Earth.
I would think that the Moon would have the most effect on the oceanic and atmospheric tides being our closest neighbor. But, I think that the orbits of the planets are affected enough by the Doppler Wobble and each other, particularly the four gaseous giants, to ever so slightly alter a planet's over cycles of time and affect a planets climate.
Gravity rules!

I don't know, but I've never seen proof that either happens...far as I can tell, the sun doesn't wobble much?
