Solar wobble - what are the effects of Jupiter and Saturn?

AI Thread Summary
The discussion revolves around the solar wobble and its relationship with Jupiter and Saturn. The initial inquiry suggests that the Sun wobbles more during a Jupiter-Saturn conjunction and less during oppositions, raising questions about the nature of this acceleration and its effects on the Sun. It is noted that the solar system revolves around its center of mass, which can be outside the Sun, indicating that the Sun experiences gravity in a state of free fall. Tidal forces from Jupiter are acknowledged, while Saturn's effect is considered negligible. Overall, the impact of these gravitational interactions on the Sun's structure and behavior remains a topic of exploration.

Hi
I came across this excellent forum :)

I am trying to figure out the solar wobble. When only looking at the Sun+Jupiter+Saturn, my intuitive interpretation is that the Sun will go faster/wobble more at Jupiter-Saturn-conjunction, and slower at oppositions. Is this correct?

If so, there seems to be an acceleration? Does the Sun "feel" this acceleration in any way? Or is it in "free fall" and does not experience any real force?

If the sun accelerates, would it have any kind of differential effect, so that the Sun is deformed or the flows on the Sun are affected?

Or does the Sun only experience the normal tidal force from Jupiter (while Saturn has a negligible tidal effect)?

Would be pleased to hear any opinions :)

Isaac Newton discovered that the solar system revolves around its center of mass. This is sometimes outside of the Sun. The bodies experience gravity as free fall. I would think that tidal forces are very small.

Asteroid, Data - 1.2% risk of an impact on December 22, 2032. The estimated diameter is 55 m and an impact would likely release an energy of 8 megatons of TNT equivalent, although these numbers have a large uncertainty - it could also be 1 or 100 megatons. Currently the object has level 3 on the Torino scale, the second-highest ever (after Apophis) and only the third object to exceed level 1. Most likely it will miss, and if it hits then most likely it'll hit an ocean and be harmless, but...
