During a harmonic convergence of the major planets does the barycenter ever leave the suns sphere?
Do you know what a weighted average is? How about balancing a balance-beam? E.G., if you have two equal weights, they balance in the center (halfway from each end). If you have one weight twice as big as the other, they balance 2/3 of the way from the light end. You should be able to do such a problem now (though if you really need to see the equation, you can google it).jim77 said:because I'm pretty dumb. I wouldn't know where to start.
Orodruin said:Another possible way of proceeding is to type “solar system center of mass” into Google.

I don't know what you have been searching for before, but all the results I got were relevant.stefan r said:Is that the best exercise for mental health? Search engines sometimes link back to physics forums. I did that search for kicks and got a link that said "the solar plexus is the center of mass of the body and the sun is the center of mass of the solar system".
Not on average. It is in Jupiter. It does not change much. The CoM of it is not though, Saturn is worth quite a punch too. However, had the OP done the minimal effort first he would not have had to ask the question in the first place. Also, if you actually do the math, Jupiter's mass puts the Jupiter-Sun CoM just about at the solar radius so the positioning of the other planets (mainly Saturn) are important as well.stefan r said:On average most of the non-sun mass of the solar system is in Jupiter.
Yeah. The search I did put a pretty/definitive picture ahead of the search results!Orodruin said:I don't know what you have been searching for before, but all the results I got were relevant.
It is also the least you can expect someone to do before asking the question. (See https://www.physicsforums.com/insights/little-excuse-ask-question-cold/)
Yeah: I made a little spreadsheet for a running tally: 107% for Jupiter alone. Another 59% for Saturn. Beyond that only Uranus and Neptune matter and not enough if Jupiter and Saturn are aligned. Earth's impact is much less than 1%.Also, if you actually do the math, Jupiter's mass puts the Jupiter-Sun CoM just about at the solar radius so the positioning of the other planets (mainly Saturn) are important as well.

9. Equation for center of mass was stolen from Wikipedia.
9.a. I should mention the fact that the first value being zero, confused me; "How on Earth can the sun, comprising 99.87% of the solar systems mass, zero out here?"...
9.b. Did some maths. It seemed to work out.
I saw that. Just didn't like it.stefan r said:The quantity m1r1 is zero because the because r1 is zero.
simply a question of the choice of coordinate system If the reference point is centre of mass of the sun, its distance is by definition zero. All the non zero terms provide the offset of the result from that zero reference.stefan r said:The quantity m1r1 is zero because the because r1 is zero.
A solar system barycenter is the center of mass of the entire solar system, including the Sun, planets, and other celestial bodies. It is the point around which all objects in the solar system orbit, and is constantly changing as the positions and masses of these objects change.
The solar system barycenter is calculated by taking into account the masses and positions of all objects in the solar system. The more massive an object is, the more it contributes to the barycenter's position. The barycenter is constantly recalculated as the objects in the solar system move and change in mass.
The solar system barycenter is important because it helps us understand the dynamics of the solar system. By tracking the barycenter's movements, we can learn more about the masses and positions of the objects in our solar system. It is also crucial for accurately predicting the positions of objects in space.
The solar system barycenter affects the orbits of planets by acting as the center of gravity for the entire system. This means that planets and other objects are constantly being pulled towards the barycenter, causing their orbits to bend and shift. The closer an object is to the barycenter, the more it is affected by its gravitational pull.
Yes, the solar system barycenter can change over time as the positions and masses of objects in the solar system change. For example, when planets are aligned in a certain way, the barycenter may shift closer to one particular planet. This constant movement of the barycenter is a natural occurrence in our ever-changing solar system.
