**The center of mass of the solar system inside or outside the sun?**

*It is a center* of mass problem. Suppose that the planets are aligned starting with the sun and ending with Neptune (since Pluto is no longer a planet). I just want to know if the center of mass is inside or outside of the sun and preferably how far it is from the center of the sun even if it is not necessary. 10 points to best answer, of course. If you can save it to be too large.

If you have a table of masses and orbital radii, you can estimate. The calculation is not difficult, just annoying. Imagine all the planets are all aligned. Calculate the moments of mass from the center of the sun. Multiply the hours of mass distance from the center of the sun and add all the products. Use the semi-major axis distance to get the answer. Our origin is the sun, he has no time of course. You'll see what planets contribute with important moments (the giant drinks) and did not matter at all. So if you're lazy, just do the 4 large gas planets. Then, divide times the total by the total mass of all the planets and the sun to get the distance to the center of gravity. I guess the result is smaller than the radius of the sun, but I do not know (apparently it is bigger, "said Bill, by just one point from Jupiter). Note that this calculation is an upper limit which greatly overestimates the usual distance from the CM because it assumes the planets are perfectly alligned which never happens in practice. (And use the semi-major axis which is the max). Normally, they vanish. It is possible that the CM is normally in the sun, but from time to time when you get a freak alignment, it takes a teensy bit. Remember that sun himself dancing around the cm and if the planets line up, it goes away. – So, according to figures the bill, the answer would "sometimes, sometimes," according to the alignments. If you want an answer to the "typical" distance cm, a good approach would be to add four times in quadrature planets rather than simple addition. So total time = sqrt ((m1 r1) ^ 2 + (m2 r2) ^ 2 + m3 (r3) ^ 2 + (m4 r4) ^ 2) Divide this by the total mass, m1 + m2 + m3 + m4 + msun, to get your cm.
