Ответ:
Assuming that the earth is the center of all coordinates. The center of mass of the earth will be located at the coordinate![x_1 = 0](/tpl/images/0366/7459/8620c.png)
To calculate the center of mass of the Earth-moon we require to proceed to the calculations given by,
Where
Replacing the values we have
We extrapolate this procedure to the sun, but now including the three bodies, in this way
So we have the two center of mass:
System Earth-Moon equal to
km
System Earth-Moon-Sun equal to
km
