2021年1月8日 · The solar system barycenter (SSB) is sometimes inside the Sun and sometimes outside. As an observer outside the solar system could detect with Doppler spectroscopy, the Sun is what's wobbling around. The Sun's offset from the SSB is a vector sum of roughly: 0.00496 au ±5% away from Jupiter; 0.00272 au ±6% away from Saturn

2021年7月14日 · As expected based on Jupiter alone putting the barycenter just outside the Sun, when all four main planets are taken into account the barycenter spends about 54% of the time outside the Sun (or the Sun spends 54% of the time further than one of it's radii from the barycenter). median r: 1.209 mean r: 1.189 max r: 2.17 fraction: 0.542

You still seem to be of the impression that the solar system barycenter is a gravitational attractor. It is not. The advantage of a SSB-centered frame is that that frame is the frame in which the equations of motion used in a numerical propagation of the solar system as a …

2018年10月16日 · As you can see from the diagrams below of the motion of the Solar System's barycenter relative to the Sun (courtesy of Wikipedia), the Sun's motion with respect to the system's barycenter is not a simple closed curve, and it doesn't have a simple period.

2016年9月1日 · Where is the barycenter between Earth and the sun? Well, the sun has lots of mass. In comparison, Earth's mass is very small. That means the sun is like the head of the sledgehammer. So, the barycenter between Earth and the sun is very close to the center of the sun. [It orbits 449 km from the sun's center.] Jupiter is a lot larger than Earth.

2021年12月16日 · The Sun's wobble around the barycenter affects other objects' velocities relative to the Sun, leading to significant fluctuations in heliocentric elements when an object is moving slowly. Far from the Sun, barycentric elements are more stable. Close to the Sun, heliocentric elements may fit the real trajectory better.

2020年8月15日 · The barycenter is closer to the more massive star than it is to the less massive star, which in turn means the gravitational acceleration toward the more massive star is greater than it is to the less massive star. The object at the barycenter will orbit the more massive star at a rate greater then the two stars orbit one another.

2021年1月13日 · The mutual barycenter of Mercury and the Sun is about 10km from the center of the Sun, which is inside the Sun. The Sun would be orbiting this barycenter inside itself every 88 days. Now, suppose Mercury and Jupiter were the only planets. The Sun/Jupiter barycenter is located barely outside the Sun (about 1.07 Solar radii or 745,000km).

2016年8月12日 · The barycenter of two masses necessarily lies on the line segment between them, and so the only Lagrangian point that could coincide with the barycenter is L1. Let r = distance from L1 to the smaller body, R = distance between the two bodies, M = mass of larger body, m = mass of smaller body.

2020年11月15日 · Does the location of the barycenter of the solar system cause the magnetic pole flip of the sun. As the planets orbit the barycenter moves from the Center of the sun to just above its surface. Sort of a Spirograph pattern with Jupiter having the largest effect. Jupiter takes 11.86 years to orbit and the suns magnetic poles flip about every 11 ...
